I need a seasoned SharePoint specialist to move a large (>1 TB) collection of content from one SharePoint Online tenant to another. The job covers planning, execution, and post-migration validation. Scope • Assess both source and destination tenants, flagging any throttling or permission issues in advance. • Design a migration approach that minimises downtime and preserves metadata, version history, and sharing links. • Execute the transfer—PowerShell, ShareGate, or comparable tools are fine so long as they meet Microsoft best-practice guidelines. • Provide clear progress reporting during the copy phase and a roll-back strategy in case of unexpected errors. • Perform post-migration checks: item counts, search indexing, and user access. Delivera...

I need a complete Azure DevOps CI/CD workflow that builds and deploys our entire solution from a single repo. Proposals. Please start your proposal with the word "OUAzure" so we know you have read everything, else your proposal wont even be read. I know the time needed so the price are really important. Build pipeline • Source contains 3 C# libraries (Fortnox, BL, Shared), 2 ASP .NET sites (Auth, API), 1 Windows Service, 3 React front-ends and an SSDT database project. • A pull request into the develop branch must automatically compile everything, publish artefacts and then trigger the Test deployment. We are not adding SonarQube or NUnit at this stage, so the default Azure DevOps tasks are enough. Release pipeline • Two stages today: Test (automatic fro...

I need a production-ready, web-based HR Management System that unifies three core areas: • Time & Attendance – real-time clock-in/out, leave management, overtime tracking, and the ability to record salary advances. • Payroll Processing – automated calculations tied to the attendance data, statutory deductions, and downloadable payslips. • Employee Management – smooth onboarding/offboarding workflows, performance reviews, and secure document storage for contracts, IDs, and policies. Security, role-based access, audit logs, and a responsive interface are must-haves. I’m open on the tech stack as long as it is modern, scalable, and well documented; propose what you do best and outline any frameworks or cloud services you plan to use. Deliver...

I need a lightweight “XL Word Pad” application whose main strength is document formatting, with special emphasis on flexible page-layout controls. The key capability I’m after is rock-solid support for column layouts—think easy switching between single-, double-, or custom multi-column views, with adjustable widths that hold their shape when the file is saved, reopened, or exported. The core workflow should feel as familiar as a basic WordPad, yet expose dedicated layout settings right on the toolbar or in a side-pane so I can set column count, spacing, and individual column width without digging through menus. If you prefer to build in C#, WPF, Electron, or another rapid UI framework, I’m open, as long as startup time stays snappy and the finished editor run...

Project Description: I am looking for an experienced full-stack developer (preferably with blockchain/DeFi knowledge) to create a high-quality, modern cryptocurrency price oracle scanner and monitoring platform, closely inspired by — specifically the "BTC Oracle Scanner" tool. This site is not a full publishing oracle like Chainlink or Pyth (i.e., it does not need to push data on-chain initially), but rather a powerful real-time monitoring, deviation detection, latency tracking, and anomaly alerting dashboard that compares BTC/USD (and potentially other assets) prices across multiple sources: CEXs, oracles, DEXs, and wrapped/bridge tokens. Core Goal & Inspiration Replicate and improve upon the functionality of : Real-time BTC/USD price pulling and comparison every few...

I currently run a Windows-based restaurant and bar billing application that handles everyday operations but is showing its age. I need it rebuilt from scratch, preserving every mission-critical function while giving me full ownership of the new source code and database. Core scope My existing system already includes restaurant billing, bar billing, inventory control, KOT printing, and state-wise excise reporting. I also rely on integrated user management, daily sales reports, a searchable customer database, and detailed excise summaries. All of these must carry over exactly as they work today. Deliverables • A Windows desktop application (preferably .NET or similar) that mirrors the current workflow for restaurant and bar billing, inventory, and KOT. • State-wise excise rep...

I want to consolidate our day-to-day job management inside Microsoft 365 and need a working solution that ties together task tracking, project documentation, and automated scheduling/reminders. Task tracking must live in an Excel-based register—think a smart workbook that captures task owner, status, due dates, and automatically stamps progress history. I still want the information surfaced in SharePoint pages or Planner boards if that makes collaboration easier, but Excel remains the single source of truth. For documentation, the build should create a SharePoint site with two libraries: one for structured files & reports and another for lighter collaboration notes. Quick links, versioning, and search need to be enabled so the team can pull up the right material in seconds. ...

I need a lightweight, standalone .exe that lets me write directly on top of any Windows desktop for live Teaching/Tutoring sessions. Core functionality has to feel as natural as a whiteboard: • Drawing tools with pressure-sensitive freehand lines • Unlimited undo / redo • An “infinite” canvas that scrolls or drags freely so I can move the work area by hand • Simple file import (PDF, PNG, JPG) to annotate over existing material A clean interface is more important than bells and whistles, but the engine must stay fast even on mid-range laptops running Windows 10/11.

I need a skilled AI / prompt engineer to build an internal system that lets me draft company letters and notesheets in a repeatable, “approved” house style. Every time a user requests a new letter, the tool should read the relevant template, mirror the exact structure and tone, then walk the user through the minimum information it still needs. Scope of the job • Documents covered: both letters and notesheets, each mapped to its own approved template. • User interaction: the workflow must blend free-text fields with dropdown menus so that routine details are chosen from controlled lists while unique content can still be typed in. • Data ingestion: the engine should be able to pull reference data from both PDF and Word sources when they are attached, parsing...

Emails hit our dedicated sales inbox every day and I want them turned into ready-to-use quotes inside MYOB Advanced (Acumatica) without re-typing a single line. From each message—whether it arrives as simple text or rich HTML—the interface must reliably read the email and interpret the content mapping it to data such as item detail, customer information contained within MYOB. Once those fields are captured, the tool should offer two modes. In automatic mode it calls the MYOB Advanced API and creates the quote immediately. In review mode it presents the parsed data in a clean pane or file so a user can double-check, adjust if needed, and then push the same “create” call manually. A setting or flag that toggles between the two behaviours will be fine. I already have...

I need a small, secure website built on .NET where registered users can log in, choose from a set of predefined templates, and instantly generate a finished PDF. The workflow is straightforward: • Users authenticate through a standard login screen (ASP.NET Identity is fine). • After login they see a dashboard listing the available templates. Payment Gateway required. • When a template is selected, questionairre is uploaded, the user completes the questionaire, the system pulls the relevant data automatically— from a SQL-based data source and from a simple form the user completes—and merges it into the template. • The completed document is rendered as a PDF, reviewed to the admin team, once approved, then offered for download and optionally emailed to t...

I need a lightweight Windows-only .exe that lets me draw directly on the screen while any application is running. The main interface can be a slim sidebar with the classic whiteboard controls—pen (with adjustable size and colour), highlighter, eraser, hand/pan tool, plus undo and redo. Two extra features round it out: • An Import button so I can pull external files straight onto the canvas. I’m open to whichever formats are easiest to implement first; images and PDFs would cover most of my use cases, and we can expand later if it’s straightforward. • A built-in “Open Browser” command. I just need a full browser window to appear inside the app; I haven’t fixed on Chrome, Edge, or Firefox, so use whichever engine integrates cleanly and kee...

I have several disparate sources holding our inventory information and I want it all pulled together into one clean, well-structured Microsoft SQL Server database file. The job is straightforward in principle: extract every piece of inventory data you can reach, reconcile duplicate SKUs or mismatched item descriptions, then load the final result into a single .sql or .bak file that I can restore through SQL Server Management Studio. Please preserve every existing field that carries operational value—quantities on hand, reorder thresholds, location codes, cost figures, and any audit timestamps—and normalise the schema where it clearly improves reporting speed or data integrity. If a field appears under different names in different systems, map it consistently; if you uncover ga...
