My Confluent Platform cluster is already up and streaming data, but the JDBC Sink Connector that should land records from a Kafka topic into Postgres refuses to cooperate. I keep getting configuration-related errors and every attempt to verify the connector’s link to Postgres ends in a failed connection. What I need from you is a concise intervention: examine the current connector configuration, pinpoint the mis-set properties that block the handshake with the database, and adjust whatever is necessary so messages start flowing into the target tables. Once it works, send a brief rundown of the changes you made and the tests you ran (topic → connector → Postgres insert) so I can reproduce or roll back if needed.
Our supervisory control platform for energy-generation sites needs to talk seamlessly to the on-site PLC systems. I need someone who already knows their way around Modbus (RTU & TCP), standard Ethernet messaging, and OPC (classic or UA) so the hand-shake between our application layer and each PLC is rock-solid. Scope The job centres on wiring up three core functions over those interfaces: • Data acquisition and historical logging into our SQL back-end • Real-time monitoring with read/write control points exposed to our HMI • Alarm and event handling with correct priorities and timestamp integrity You will work against the existing tag list, meet our naming conventions, and document every register or node you touch. I can provide VPN access to a test PLC plu...
I need a single SQL statement that I can paste straight into Microsoft Access to uncover every pair of classes that share siblings across them. In my data: • Student, Class and StudentClass are the only tables involved. • Sibling relationships are defined by a matching parents email address stored on each Student record. • The required result set is one row per class pair, plus a concatenated list of the sibling names in that pair, matching the pattern: ClassA – ClassB Joe Smith, Jenny Smith Tom Toad, Terry Toad Deliverable – A ready-to-run SELECT query in Access SQL that produces the above output. – A brief comment block explaining any joins, GROUP BY logic or string-aggregation technique you use so I can adjust it later if table name...

I need someone who can both build and maintain our UiPath automations as well as Pega automation. This role requires expertise in both UiPath and Pega RPA technologies. The focus is maitaining and supporting current UiPath Automations, while also working on migrating them to Pega Platform. This person must be able to work under minimal supervision, reaching out to stakeholders, project managers, etc as needed to get the job done. We work in weekly Agile sprints and track tasks in Jira, so comfort with that cadence is helpful. Day to day you’ll likely touch UiPath Studio, Orchestrator, Pega 8.x, SQL Developer, Postman and Git. Deliverables • Fully tested automation projects • Maintaining and Support of current UiPath automation in production • A concise run-book an...
I need a complete, working Fitness Center Management System built with Python and an SQL back-end (database name: FitnessCenter). The program will run in a simple text-menu interface and use embedded SQL calls to handle all data operations. Core workflow • Members, instructors, fitness classes, and registrations must be creatable, editable, or deactivated while respecting business rules: class capacity limits, no duplicate registrations, and only active members can book. • A first-come, first-served waitlist kicks in automatically when a class reaches capacity; as soon as a spot frees up the next person on the list is promoted and notified in-system. • Searches should let me pull up a member’s schedule or a class roster instantly. Technology notes Standard Python...

I have a CSV that holds around 9,000 physical products and I need a complete WooCommerce store set up to house them. The file contains the product details only, so before the import you’ll build a clear hierarchy of categories and sub-categories, map every item to its proper place, and make sure the catalogue feels intuitive to shoppers. If the job calls for some quick PHP snippets, SQL tweaks, or another bit of custom code to clean the data, that’s expected and welcome—the goal is a flawless import with images, prices, stock levels and SEO-friendly slugs intact. Deliverables • Fresh WordPress + WooCommerce installation on the server I provide, using a lightweight responsive theme. • 9,000 products imported with all metadata, images and variations function...
I already move comfortably around Ignition’s Designer but want to push past the intermediate plateau, so I’m looking for a mentor who can meet with me live and guide me through the tougher corners of the platform. Our sessions will be strictly one-on-one, delivered online through screen-sharing (Zoom, Teams or similar), and paced around my real-world projects so everything we cover is immediately applicable. The three areas I need to master are • Scripting & automation (Perspective and Vision, Jython, tag event scripts, gateway timers) • Database integration (SQL queries, named queries, store & forward, best-practice schema design) • Alarms & notifications (pipeline logic, ancillary scripting, on-call rosters) I’ll come prepared with a...
I have multiple raw CSV files that I need explored and summarised. The task is strictly descriptive analysis: think counts, averages, distributions, correlations and any clear-cut insights you can surface without modelling or forecasting. You are free to import the data into the SQL environment of your choice or work directly with the flat files—whatever lets you query efficiently and keep the process transparent. I simply need clean, well-commented SQL (or a reproducible notebook, if you prefer a hybrid workflow with Python + SQL) plus a concise findings report. Deliverables • SQL scripts or notebook used for the analysis, fully annotated • A short results document (PDF or Markdown) highlighting key metrics, tables/figures and your interpretation • Clear i...
I need a hands-on mentor who can take me from absolute beginner to confident BigQuery user in just seven days. My priority is to get comfortable writing efficient SQL queries inside BigQuery, understanding how the underlying storage works, and seeing how those queries translate into real business insights on live data. Here’s the rhythm I have in mind: daily one-on-one video calls (60-90 min each) where you walk me through practical scenarios drawn from your own production experience. After every call I’ll work through the same dataset on my side, then we review the results at the start of the next session. By the end of the week I should be able to design a schema, load data, build and test complex queries, and explain the cost implications of each step. What I value most is...
I maintain a Python script that prepares data and pushes it into Google BigQuery, but the code has grown messy. I want it refactored so that any developer can open the file and understand what’s happening at a glance, then watch it load cleanly into my BigQuery table. Here’s what I need from you: • Put readability first. Rename variables so they instantly convey intent, weave concise yet helpful inline and block comments throughout, and reorganize the code into neat, logical sections or functions. • Stay faithful to PEP 8 standards and keep an eye out for anything that could trip up future performance, but speed tuning isn’t the main goal—clarity is. • Verify the end-to-end pipeline: authenticate with my service-account JSON, run the script, an...
I have just moved my accounts to Tally Prime and now need a professional who can turn it into a fully working environment and keep my GST obligations on track. The scope is three-fold: configure Tally Prime from scratch so that my ledgers, GST masters, stock items and reporting are all ready for day-to-day use; complete the GST registration process and obtain the GSTIN; and handle the regular GST return filings once the registration is active. All historical data is already in order, so no migration work is required. What I’m looking for is someone who knows Tally Prime inside out, understands current GST regulations, and can set up clean, audit-ready books. Please outline your approach, any similar projects you have completed, and the timeframe you’ll need to finish the ini...
I need a clear, reproducible workflow that lets GitHub Copilot sit seamlessly inside Databricks notebooks and VS Code so we can automate code generation and analysis across our data platform. The focus is on day-to-day tasks: writing and debugging Python/PySpark, generating robust SQL, and transforming data with PySpark, generate testscripts based on requirements, ‑ exactly where Copilot will save us the most time. Our team is comfortable with Python, PySpark, SQL and Git and already works in Databricks at an intermediate level, but we’ve never wired Copilot into this environment. I’m looking for someone who can: • Configure Copilot for both VS Code and the Databricks notebook experience while keeping Git history clean. • Demonstrate automated code suggestions, in...
I have two VOIP call-detail-record files that are at the centre of a billing dispute and I need a clear, defensible comparison of them. The goal is to line up the calls in both files, calculate each side’s duration, and show me only the cases where those durations don’t agree. The final deliverable must be a single CSV file that I can forward to the carriers as evidence. Deliverables • A consolidated CSV that pairs matching calls, shows duration A vs. duration B, and includes both the raw difference and any percentage variance. • Only the calls with unmatched durations should be highlighted or extracted; fully matched records don’t need emphasis. • My two original CDRs returned untouched, plus any script, query, or workbook you build so I can rerun the...
We are facing an issue in OTBI with navigation links between two analyses based on a custom subject area. The first analysis (Main Report) contains a column called PERIOD, which is used to create an Action Link that navigates to another analysis (Pre_approved_Overtime_Summary_DM). The target analysis has the same column PERIOD and its filter is set as “is prompted”. When we click on a period value in the Main Report, the navigation opens the target analysis successfully, but the filter is not applied — it shows all data instead of filtering by the selected period. However, when we create a copy of the target analysis and use the same Action Link, the filtering works correctly. That means the navigation and parameters are configured correctly, but the original analysis ...
I need a data-savvy freelancer to take my raw customer data and turn it into an interactive Power BI dashboard that highlights behaviour patterns and key KPIs. You’ll start by removing duplicates, handling all missing values, and standardising every date, currency, and categorical field so the model is rock-solid. Once the data is tidy, build a visually engaging report in Power BI with slicers, drill-throughs, and clear storytelling visuals that make it easy for stakeholders to explore churn rates, lifetime value, and segment performance on their own. Feel free to use Excel, SQL queries, or Python scripts during prep—as long as the final PBIX file connects cleanly to the revised dataset and refreshes without errors. Deliverables: • Cleaned dataset (same format as s...
I need a lightweight Windows-based application that lets plant operators enter readings directly into a digital logbook. Each entry must be automatically time-stamped and saved to a local server so supervisors with admin credentials can review, search, and export the data for reporting and audit purposes. Key requirements • Windows desktop UI that is easy for non-technical operators to learn in minutes. • Two user roles: Operator (data entry) and Admin (full access, edit, export, audit trail). • Local network deployment—no cloud—so an on-prem SQL-based back-end or similar file database is fine as long as it runs unattended and can grow over time. • Built-in filters and export options to Excel/PDF for quick shift reports. • Straightforward i...

I need a seasoned data engineer who can move key datasets out of Sage 300 Construction & Real Estate and land them cleanly in my Azure Data Lake. The scope starts with two data domains—financial data and project-management data—pulled through the Sage 300 API. Once the raw tables are in the lake, I want robust relationships built so that: • financial data can be joined directly to project data • those joins remain extensible enough to accommodate future links to external data sources (for example, CRM or scheduling tools) With that unified model in place, the final step is a set of Power BI dashboards. The first release should surface revenue-and-expense trends and highlight project completion and performance metrics. Visual clarity, fast refresh times, and cl...

I run a wholesale business that deals exclusively in silver articles and I need a Windows-compatible, command-line billing program that streamlines our day-to-day operations without the overhead of a graphical interface. The tool has to feel snappy inside the terminal yet cover every task we handle at the counter and in the back office. Core features I must see on first delivery: • Inventory management – update stock in real time as items are bought or returned, track quantity by weight or piece, and flag low-stock thresholds. • Customer database – create, edit, and search customer records quickly; basic contact info is fine, but it must also remember each client’s last purchase. • Sales reporting – daily and monthly summaries exportable to CSV...
MUST BE BASED IN BUENOS AIRES, ARGENTINA. I have a green-field web application to build and I need a seasoned hand to lead the technical work from Buenos Aires, Argentina. The stack is firmly rooted in .NET and C# with a SQL Server back-end, so a minimum of six years’ production experience in those technologies is non-negotiable. You will be shaping architecture, writing clean, testable code, and guiding the long-term health of the solution. Day-to-day collaboration happens in English—calls, written specs, and code reviews—so near-native fluency is essential. Proximity matters too; occasional on-site sessions in the city keep the team aligned and moving quickly. While the immediate focus is the core web platform, future sprints may involve data processing in Python or s...
I have two existing analyses in Oracle Fusion OTBI that must be filtered together through a single column so I can explore the results side-by-side for deeper data analysis. The goal is to pass a value chosen in one analysis (or a dashboard prompt) directly to the other, ensuring both refresh in sync and stay consistent even when end users drill or pivot. Here is where I’m at: • Both analyses are already built and saved in the same dashboard page. • What’s missing is the joining filter: a prompt or column filter that seamlessly binds them, whether through a master-detail link, a presentation variable, or any method you find most reliable inside OTBI. • Once complete, I need to understand the steps so I can replicate the approach with future reports. Deliver...
I’m putting together a full-featured e-commerce web application and I need the server side to be rock solid. The stack is .NET MVC with a REST-style API; C# will be the main language, though you’ll see a little JavaScript on the edge for real-time interactions. The store itself must do more than handle products and checkout. I want the social layer built in from day one, so the API has to expose: • User profile endpoints (registration, authentication, avatar upload, settings) • A private one-to-one messaging system with conversation history and unread counters • A news-feed style timeline where users can follow activity, like updates, and comment Beyond those social features, the usual e-commerce flows—product catalog, cart, payment integration...
I want a Power Automate cloud flow that copies the values held in our on-premises SQL Server table “Project Number” into the SharePoint Online Term Store. Only that table is in scope—no other customer, product, or order data. The flow must: • Connect through the on-prem Data Gateway to read the Project Number table. (Already DONE) • Create, update, or deprecate terms so the Term Store mirrors the current SQL list. • Run automatically once every 24 hours without manual intervention. Please build and test the flow in my tenant, document the configuration steps, and give me a quick guide for future maintenance. Successful delivery is a working scheduled sync plus the hand-off notes so I can import or re-create the solution in another environment if...
I need a full-scale Online Management System that lets me run several hotels from one place. The platform must open with separate logins for admin and on-site staff, then guide us through everything that happens in a property—from showing vacant rooms to balancing the books at month-end. Core workflow • Inventory: Each hotel lists its 1BHK, 2BHK and 3BHK options, tagged as AC, non-AC or cooler, with independent pricing and location metadata. • Public booking: Guests land on a home page that instantly displays every vacant room. They choose a room, enter their details and pay either in full or partially. • Alerts: Two hours before a scheduled checkout the system fires a notification so reception can prepare. • Cash flow: I need day-wise, customer-wise and ...
I need a relational database that catalogs every emergency-service asset in the State of Missouri. The final product should let a user quickly cross-reference police departments, fire services, medical services, 911/PSAP centers, and hospitals by county, city, ZIP code, and agency type. Scope • Design a clean, well-normalized schema (PostgreSQL or MySQL preferred) that links agencies, locations, contact details, service areas, and any applicable certification or dispatch information. • Populate the tables with the most current publicly available data for the entire state, checking state directories, county records, and individual agency websites so the information is as complete and accurate as possible. • Provide importable .sql files plus a short read-me explaining...

I have a fully-functioning Tableau workbook that connects to an SQL database. I now need an exact replica of that model, but built so it also incorporates two additional existing worksheets I will provide. Beyond the straight copy, I already have a short checklist of improvements—layout refinements and one calculated field change—to be worked into the new version. You’ll get the current .twb file, credentials for the same SQL data source, and the two sheets I want merged. Once your updated workbook mirrors the original visuals, links flawlessly to the database, and reflects the requested tweaks, simply return the packaged file for review. When you reply, point me to past Tableau projects that show you can pick up an existing structure, duplicate it cleanly, and make foc...
I run a logistics company and I’m tired of copy-pasting numbers all day. I want a Google Sheets workflow that produces clean, reliable reports for me instead. The only thing I need automated right now is report generation; data entry and live inventory tracking can stay manual for the moment. Here’s what I’m looking for: • report types must be produced from my raw data: Sales, cost, fleet utilization, maintenance and overall Performance. • Each report should refresh on three schedules—daily, weekly, and monthly—using time-based triggers so no one has to remember to press a button. • The solution needs to live entirely in Google Sheets. If Apps Script, QUERY, IMPORTRANGE, or simple SQL connections are the best way to get there, that’...
I need a Windows-based AI agent that connects directly to my ContPAQi SQL Server databases and lets me pull the exact business data I ask for without manual queries. The goal is to have a small desktop application or service I can install on my PC that understands natural-language requests in Spanish and quickly returns: • Excel or PDF reports of sales data, ready to print or share • On-screen summaries of business, client, supplier, product, and service status • Fast access to accounting figures and simple dashboards Sales reports are my priority. At a minimum the agent must provide: 1. Totales de ventas por período 2. Ventas por cliente 3.

Core schema • Clients: name, address, email, phone, contact • Staff: name, employee #, location • Offices: name, address • Services: description, standard fee Web interface • Clean, responsive screens to enter and update records in each table. • Secure sign-in with two roles—Admin (full control) and User (data entry & report viewing). • Simple navigation so staff can start tracking work right away. Work-tracking workflow 1. User selects a client, chooses a service, assigns themselves (or another staff member), and enters hours spent. 2. The ...
I have raw sales exports piling up and need to turn them into clear, decision-ready insights. The single focus is to identify trends—especially product performance trends—within that sales data. You’ll start by cleaning and structuring the CSV/XLSX files I provide. From there, use the analytic stack you’re most comfortable with—Python (Pandas, NumPy), SQL, R, Power BI, Tableau, or Looker Studio—to explore the data and uncover which products are gaining traction, stagnating, or slipping. Deliverables • A concise report or deck with charts that highlight key product-level trends and explanations of what’s driving them. • The cleaned dataset plus all reproducible code or notebooks. • A brief walkthrough (recorded or live) so...
I’m building a web application focused on customer-data management and I’m looking for a developer who feels at home in both the React front-end world and the C# / SQL / Azure back-end stack.

Nice-to-have If you can layer in a lightweight AI touch—such as an Azure OpenAI endpoint that suggests next-best actio...
I run an online retail store and want clear, evidence-based direction for our next marketing moves. You’ll work exclusively with our transactional data to uncover what, when, and how our customers buy. Here’s what I need from you: • A concise analysis (Python, R or SQL) that highlights purchase frequency, average order value, and any standout buying cycles. • A first-pass customer segmentation model—think RFM or a similarly lightweight approach—so I can see which shoppers deserve extra attention. • A brief, plain-language report summarizing the insights and the actionable steps they suggest based on submission guidelines I’ll provide the raw transaction files and the mandatory “Submission Guidelines – Online Retail.” ...
I’m running a product that relies on the Lotus 365 gaming API. The front end is fine and authentication works, but a logic flaw in the gameplay endpoints is producing incorrect results during live play. I need the bug traced, patched, and fully tested so scores and outcomes are once again reliable. Scope of work • Inspect current Lotus 365 API integration and pinpoint the faulty game-logic routine. • Develop and apply a clean fix without breaking existing authentication or UI flows. • Supply regression and unit tests that prove the logic now behaves as intended. • Deliver a concise technical report outlining cause, solution, and any follow-up recommendations.

I need an experienced SQL specialist who can step straight into our pharmaceutical data environment and tighten every performance screw. My priority is query performance tuning and a thoughtful indexing strategy, followed by deep execution plan refinement so that reports inside Dataiku render quickly and reliably. Current challenges • Queries touch multi-million-row clinical and sales tables and now run in minutes instead of seconds. • Indexes have grown organically and no longer align with business-critical workloads. • Dynamic reporting in Dataiku is sluggish, putting analysts on hold and raising compliance concerns about data integrity. What I expect from you 1. Review existing SQL code and indexes, then deliver a clear, actionable tuning plan. 2. Restructure ...
I have an existing PHP website—around 30 public-facing pages plus a small admin panel—and I now need it rebuilt in Net beans and SQL as backend. The goal is a one-to-one conversion that preserves every current feature and keeps the exact same design and layout. No new functionality is required and the site has no third-party integrations, so the task is purely a straight port. What I’m looking for: • A NetBeans for the front end. • A clean SQL backend (tables can follow the current MySQL schema). • Basic setup instructions so I can deploy the project locally and on my server. Please focus on producing working pages that match the existing look and behavior; deep refactoring, performance tuning, or UX redesigns are not in scope right now. If you have ...

I need a lightweight Windows desktop application that lets me manage records stored in a SQL database. The goal is to keep things simple—just the core CRUD features. Core needs • Display records in a clean, sortable grid. • Add, edit, delete, and search entries through a user-friendly form. • Basic validation (required fields, correct data types). • Export the current view to CSV. Deliverables • Compiled installer or portable EXE that runs on Windows 10/11. • Full, well-commented source code so I can maintain it later. • A brief read-me explaining setup, connection string placement, and any third-party libraries used. I’m comfortable with C#/.NET, WinForms, WPF, or a similar native stack—as long as it’s stable and easy...
I need a quick, working proof-of-concept ETL pipeline built by someone who has real-world experience moving data end-to-end. The job is intentionally lean: • Connect to at least one common source (a simple SQL table, NoSQL collection, or a lightweight API—whatever you can access easily for demonstration). • Extract a small sample dataset, transform it with a couple of clear, documented steps, and load it into a destination of the same family or a flat file. • Package your work in a git-friendly structure with a short README explaining prerequisites, how to run the flow locally, and how to swap in other sources later. Tool choice is open. If you prefer Apache NiFi, Talend, or Apache Airflow, go for it; if another open-source option will get the job done faster...
