I need an engineer who already works comfortably with the MZ Automation (openIEC61850) library to build a complete, Edition 2.1–compliant SCL file for one of our Smart Grid systems. All logical nodes to be modelled are spelled out in my internal specification document, so you will not have to guess any class names or data objects; just implement exactly what is listed. I need SCL files and tools (preferably automatic or semi-automatic) to generate the required files (ICD, CID, SSD, SCD) starting from our plant configuration file for each specific installation in the future. Alongside the SCL you will prepare the full set of IEC 61850 conformance paperwork: • PICS • PIXIT • TICS • MICS

I have a very small Python snippet that prints “Tumi voter” when age is 18 or more and “Tumi voter na” otherwise. I want this turned into a clean, beginner-friendly example that actually asks the user for their age, validates the input, and then displays the same Bangla messages. The task is deliberately simple: create a single .py file that runs from the command line, requests the user’s age, handles non-numeric input gracefully, and prints the correct message based on the age entered. Keep the code concise, well-commented, and organised so it can be shown to new learners as a model of good practice in Python.

I need a TDL file to customize the Ledger Vouchers screen in TallyPrime by adding 4 specific features to the right-hand sidebar (Button Bar). Please check these requirements: 1. Web Link: Add a button. When clicked, it should directly open our website in the default web browser. 2. Show/Hide Narration: A toggle button to quickly show or hide the narration for all entries in the current ledger view. This helps in cleaning up the view when I am only looking at amounts. 3. Narration Filter: A search/filter button specifically for the Narration field. I should be able to type a keyword (e.g., 'Cash' or a specific 'Ref No') and the screen should only show vouchers containing that text in the narration. 4. Replace Ledger: This is for bulk editing. I want to select ...

I'm seeking an experienced C++ developer to write a patch for an old Windows 98/XP game to make it stable on Windows 10. The game currently crashes or freezes during gameplay, seemingly at random after playing for a while. The game is designed for 32bit, not 16, so it should probably be a bit easier. But I have very little knowledge of coding Requirements: - Expertise in C++ - Experience with legacy software and Windows compatibility issues - Ability to diagnose and fix crashes in games Ideal Skills: - Game development background - Familiarity with Windows 10 internals - Strong debugging skills

My current workflow already relies on , but I’m hitting limits with its out-of-the-box functionality. The project centers on true custom feature development—expanding so it fits my exact use-case rather than forcing my process to adapt to the platform. The work starts with a quick review of the existing setup, followed by a short requirements session where we pin down what the new feature must do, how it should be accessed, and any guardrails around performance or security. From there, the task moves into design, coding, and rigorous testing inside a staging environment to be sure everything runs smoothly once promoted to production. Deliverables • Complete source code and configuration for the new feature • Clear deployment notes and end-user documentation ...

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’m open to your preferred framework—Electron, WPF, C++, or another—so long as the final deliverable is a single installer or portable .exe. Please include: 1. A bri...

I need a fully-functional Harness pipeline that covers both Continuous Integration and Continuous Deployment for three distinct environments—Development, Staging, and Production. The goal is to push code from Git through automated build, test, and deploy stages with zero manual touchpoints and clear promotion rules between each environment. Along the way, I want the pipeline to trigger my existing continuous testing suite and publish results inside Harness so release decisions are data-driven. After deployment, success metrics, logs, and alerts must flow automatically into the monitoring and logging stack I already use (Prometheus + Grafana; open to other native Harness integrations if they make life easier). Because this is a configuration-heavy task, I’d like the end result ...

Hi I will share the details with the shortlisted candidates. thanks

I need a small, Windows-friendly Python script that will open a real browser with Selenium and wipe large batches of content from my X (Twitter), Facebook, and Instagram accounts. Because my X account sits on the free API tier I keep running into 403 errors, so this project must rely solely on browser automation—no official APIs or paid third-party tools. Here’s what I’m after: the script launches from the command prompt, asks for (or reads from a .env) my login credentials, signs in, and then iterates through all visible posts, tweets, and reels, deleting each one until none remain or until it hits an optional stop condition such as a date or a post count I can set. A simple console printout like “Deleted tweet #42” is enough for logging; I don’t need ...

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 need a fully-coded Relative Strength Index indicator that plugs straight into Quantower via its open API. The core requirement is simple: the look-back period must be user-adjustable from the platform’s settings panel so I (or any trader) can fine-tune it on the chart without opening the source. Please keep the script lightweight, coded in C# as recommended by Quantower, and use the platform’s standard drawing and event hooks so it behaves exactly like a native study—automatic repaint on bar close, proper scaling on sub-panes, and settings persistence between sessions. I am only targeting this one technical indicator right now, but if you design the class structure cleanly, adding overbought/oversold bands or divergence logic later should be straightforward; solid...

Our self-hosted GitLab instance has grown quickly and the cracks are beginning to show. I now need a full, end-to-end review of the entire implementation—from the way pipelines are defined to how repositories are organised and, most urgently, how user access is controlled. Current Version - 18.7 Current pain points • Access permissions are inconsistent and hard to trace. • Merge-request approvals don’t always follow our intended flow. • User-role management has become manual and error-prone. Beyond those control issues, I’m sure other inefficiencies have crept in, so I’d like fresh eyes on the entire setup. Scope of work 1. Audit the existing GitLab configuration, including runners, CI/CD pipeline definitions, repository structure and vi...

I need a fluent English speaker who can jump straight into handling both inbound and outbound calls with our business partners. The role sits at the intersection of customer happiness and light technical troubleshooting, so you’ll spend most of your day guiding partners through product-related questions, documenting each interaction in our CRM, and making sure every conversation follows the script and brand tone I’ll provide. Because you’ll be the first voice many partners hear, I’m looking for someone who stays calm when lines are busy, keeps notes organised, and can translate a technical answer into plain language on the fly. Prior technical support experience is essential—if you’ve ever walked someone through a configuration step or explained why a...

I already have a working desktop budget-management application and now I’m ready to extend its capabilities. My priority is to add new features rather than fix bugs or work on performance tuning, so I need someone who enjoys feature development and can plug into an existing codebase quickly. The current build is stable and fully documented; you will receive the repository and a brief walkthrough of its architecture at the start of the engagement. From there, we’ll outline the features in detail together—think smarter reporting views, additional expense categories, maybe a quick-export to CSV/PDF—then agree on a milestone plan so you can deliver iterative updates and I can test on my side. Deliverables (per milestone) • Updated source with the agreed fea...

I need a strong developer who can debug TypeScript code with ease and assist with deep debugging and troubleshooting of my current script, including root-cause analysis, refactoring fragile logic, and improving overall maintainability.

I have a working file-transfer script that already handles all the send/receive logic; now I need it wrapped into a polished desktop application that installs cleanly on Windows, Linux and macOS. After installation, the embedded sync-engine must run automatically at regular, short intervals—every few minutes—without user intervention, quietly polling our remote server and pushing or pulling any file changes it detects. What I still need built is the installable package itself along with a lightweight settings interface that supports both light and dark themes. The GUI only has to let users confirm the target folder and, if they wish, pause or resume syncing, so the design can stay minimal yet visually impressive. Under the hood the sync routine should launch on startup (servic...

We are a hotel using a specific electronic door lock. We need to integrate these locks with our Property Management System (PMS) to automate keycard management. The lock company cannot provide an API or documentation, so we need to determine the communication protocol and build a custom interface.

I have already wrapped up all product design, UX, and UI work for my new Android app and now I need the engineering muscle to bring it to life. Your main mission is two-fold: first, build system-level battery-optimization enforcement so the app behaves responsibly in the background without being killed by Doze or aggressive OEM policies; second, hook the project into Firebase. On the Firebase side, the app must support Authentication and Realtime Database right out of the gate, with Cloud Messaging for push notifications and Remote Config for on-the-fly feature tuning. For sign-in flows, I only need email-and-password and Google Sign-In. You will be working from a clean, well-commented repository that already contains the complete UI layer. I’ll provide the Figma files, current Gra...

I’m building Mirai Album, a desktop application that lets photographers design complete wedding albums without leaving one streamlined workspace. The program must run smoothly on Windows 10 and Windows 11, install with a single click, and feel at home on modern systems.

I’ll supply brand assets and preliminary UI mock-ups; you focus on the engineering. Core feature set • Integrated photo-editing tools: filters & effects, precise cropping/resizing, and dependable red-eye removal, all updating in real time even with large JPEG or RAW files. • Intuitive page and spread layout with drag-and-drop, unlimited undo/redo, and liv...

I need a compact piece of code that can create an L1-eligible product listing on the Government e-Marketplace (GEM) portal. The sole focus is the “Product on GEM site” functionality— no user management, payment handling, or analytics at this stage. The script should: • Authenticate with my GEM account (I’ll supply sandbox credentials). • Push all mandatory product data— title, specifications, price, images— so the item appears in the catalogue and is flagged as the lowest (L1) offer when applicable. • Return the product ID or any response GEM provides that confirms the listing. Language can be Python, Node.js, or another mainstream stack if you can justify the choice. Keep the code clean, well-commented, and drop a short README...

I’m building a product, not a demo and not a quick MVP. I’m looking for a a small and strong team who wants to help build something foundational and stay involved, not someone who just wants to close a ticket and move on. The work is split into two tightly connected parts: 1) Code name - RAYA This is the core platform. RAYA is an AI orchestration system — basically the “brain” that handles AI workflows, task routing, logic, decision layers, and integrations. It’s not tied to one product. The idea is to build this once, properly, so it can power multiple products over time. Think platform first, product second. 2) Code name - LEO LEO is the first real product built on top of RAYA. It’s focused on jobs, talent, hiring workflows, 6 other field niche a...

My Ruby (Rails) API usually answers in milliseconds, yet at unpredictable moments the same endpoints take seconds to return. Standard logs show no spikes in traffic, and CPU / memory look normal, so I suspect a hidden bottleneck—perhaps DB connection exhaustion, an elusive N+1 query, or a background job starving Puma threads. You will dive into the codebase, profile the request/response cycle, pinpoint the root cause, and supply a clean fix that restores consistent response times. Feel free to use rack-mini-profiler, New Relic, Scout, or your preferred Ruby profilers; the server runs Ruby 3.1 and Rails 7 on PostgreSQL. Deliverables • Diagnostic report summarising findings and root cause • Patch or pull request with the optimised code/configuration • Before-an...
