I need a Windows application capable of reading data from DNP3 devices over Ethernet and exposing it through an OPC UA Server. I don't have a strict preference for the environment: you can work in Python or Visual Studio/C#; the important thing is that the final solution works stably and is delivered with all the source code well documented. Main Scope • DNP3 communication module: detection, connection, and periodic reading of points (analog, binary, counter). • Embedded OPC UA server: real-time publication of the read variables, with a clear node structure navigable from any standard client. • Graphical interface: must allow adding, editing, and deleting devices and variables independently (names, addresses, types, intervals, etc.). • Basic persistence: confi...

From Pakistan or India Only new Junior Level Work Needed. I maintain a small-to-medium ASP.NET solution written in C#. Day-to-day work occasionally piles up, so I want to bring in a junior developer who can jump into Visual Studio, pull the latest branch from Git, and tackle clearly defined tasks as they appear. Typical assignments will involve: • Updating or refactoring existing C# classes to keep the codebase clean and readable • Implementing straightforward pages or components in ASP.NET (MVC/Core) under guidance from my side • Writing concise unit tests so we keep coverage intact • Checking in changes via pull request and responding to code-review comments You will always receive a ticket that describes the goal, the current behaviour, the expected result, a...

I need my existing cloud-hosted application brought up to date. The codebase is currently on .NET 6 and must be cleanly converted to .NET 10 while keeping every feature intact. The focus is entirely on the back-end: business logic, API layers and the database integration that connects to Azure SQL. Along the way, any NuGet dependencies that block the version jump need to be replaced or upgraded, and build pipelines in Azure DevOps adjusted so the new build targets compile and release without manual tweaks. Once the code compiles on .NET 10, it has to be redeployed to my Azure environment behind Azure Bastion. A successful hand-off means: • the application runs in the new runtime without warnings or breaking changes • database migrations (EF Core) run automatically on f...

I’m putting together a web application that blends a C#/.NET back-end with existing PHP components, all running on a single MySQL database. The core challenge is to turn raw transactional data into clear, actionable insights—interactive dashboards, drill-downs, exports, and scheduled reports—so I’m looking for someone comfortable moving fluidly between both stacks. You’ll be free to suggest the specific .NET flavour (ASP.NET Core, MVC, Web API, etc.) and your preferred PHP framework, as long as everything threads cleanly into MySQL and remains portable across typical Linux or Windows hosting. While data analytics is the headline feature, clean architecture, modular code, unit-tested endpoints, and solid security practices are just as important because this pr...

I need a streamlined, reliable automation layer for my BIJILITRA operation. Right now our day-to-day work still relies on a mix of spreadsheets, a small SQL store, and a couple of home-grown tools, and it slows us down. I’d like you to analyse the current flow, pinpoint the steps that consume the most time—whether that ends up being data entry, ad-hoc reporting, inventory updates, or something else—and then engineer an automated process that removes as much manual effort as possible. Your solution should: • Plug into (or sensibly replace) our existing Excel and SQL assets without disrupting live data. • Include clear, commented code or low-code components that my team can maintain. • Ship with concise user documentation and a brief hand-off session so ...

I’m ready to move an idea from concept to a fully functioning desktop application and need a full-stack developer who can own the build end-to-end. You’ll design the interface, wire up the business logic, handle local data storage or remote API calls if needed, and package the final executable so it installs cleanly. My priority is a smooth, responsive user experience paired with a clean codebase that I can maintain long-term. I’m flexible on the tech stack—whether you prefer Electron, .NET (WPF / WinUI), JavaFX, or another modern framework, bring the tools you’re most productive with and outline why they’re a good fit. When you reply, focus on your experience delivering desktop apps: languages, frameworks, and any examples that demonstrate solid UI wo...

I need a small-scale Library Management System built with C# and SQL Server that targets just one user group—students. The single workflow I want implemented is book borrowing handled through an online request form. At minimum, students should be able to: • Sign in with a basic account • Search or browse the book catalogue • Submit an Online request to borrow a selected title • View a confirmation that their request has been recorded Behind the scenes the system must store all catalogue data, user accounts and borrow-request records in SQL Server. Clean, parameterised queries or stored procedures are expected so the code is safe and easy to extend later if we decide to add faculty or librarian roles. Deliverables • Complete C# source (desktop WinF...

I already run my business on a desktop-based invoicing tool and can supply its full source code. I want an exact replica built from that code, retaining the entire workflow and interface, but I also need a seamless WhatsApp integration so I can share invoices or payment reminders directly from the app. The new build must run reliably on Windows, match every existing screen and function, and keep all current features—client management, payment tracking, and automated recurring invoices—intact. While you are free to refactor or modernise the codebase for maintainability, the user experience should feel identical to what I have today. Key deliverables: • Compiled Windows installer and signed executable • Complete, well-commented source code • Fully functional ...

I’m expanding a US-based SaaS product team and need an experienced .NET engineer who can own our customer-facing web applications while helping to ship production machine-learning models. Most of our stack lives in C# with ASP.NET MVC and Entity Framework, but our ML pipeline runs in Python, so you should feel at ease moving between both worlds—writing clean controller/API code, optimising queries generated by EF, and wrapping or calling Python models for inference and training. Selected technologies you must already handle: • Entity Framework • Python • AI (machine-learning models) Prior experience at a U.S. company is strongly preferred because we follow U.S. business hours (roughly 9 am–5 pm EST, Monday–Friday). If you enjoy bridging full-...

I need an experienced .NET developer—five years or more working hands-on with C# and SQL Server—to step into an existing web application and keep it moving forward. The solution is already live and in daily use, so you’ll be working against a real-world codebase, not a green-field prototype. The core stack is ASP.NET (a mix of MVC and newer .NET Core services) with a SQL Server back-end. I rely on Entity Framework for data access, Git for version control, and a straightforward CI/CD pipeline. You should feel comfortable reading and refactoring legacy code, designing new features that slot cleanly into established patterns, and optimising T-SQL when a query starts slowing things down. Key things I’ll be asking you to do: • Review and refactor existing mo...

I'd love to connect and discuss potential collaboration opportunities.

I need an experienced .NET Core developer to plug full FASTag capability into my existing parking management platform. The RFID readers are already in place and streaming tag IDs; what’s missing is the software layer that talks to the FASTag service provider and folds those events into our business logic. Here is what the work entails: • Entry and exit processing – build secure REST endpoints that receive the tag read, validate it against the provider’s API, open the barrier, and persist the transaction with status codes for later audit. • Reconciliation and reporting – create automated, scheduler-driven jobs that pull settlement files, match them to our local ledger, flag discrepancies, and generate daily CSV-based reports. Beyond those core items, th...

I need a Windows-based application that talks directly to our Additel digital pressure gauges and Hydratron transducer, captures live pressure-temperature data, and drives the entire hose pressure-test workflow to NATA and current Australian Standards. The program must let a Technician log in, select a hose specification, enter temperature and target pressure, then automatically calculate the correct test duration and pass/fail limits. While the test is running it should stream readings from the instruments, display them in real time, and store everything in a SQL Server database. Once complete the software must produce a pressure-versus-time graph, compile all critical measurements, and generate a tamper-proof test certificate that satisfies NATA formatting requirements. Acceptance crit...

I’m extending our existing web-based application to cover the full accounts-receivable cycle. The new module must sit inside the current web app, so please plan your code to use the same tech stack, database, and authentication flow that is already in place. Core workflow • Finance reviews each quotation request that the team already creates in the system. • From that same screen Finance can produce a Invoice from system or from other application and upload the invoice against that quotation request and choose the due term (Net 0, 10, 30, 60, 90, 120). Support team will review it and click to send the invoice to client from application. • Issued invoices appear in a master list; any request that is still “uninvoiced” lives on its own page for quick fo...

I am launching a new web application and want the entire backend built in F#. The project must include rock-solid user authentication and two external API integrations: a payment gateway for transactions and social-media endpoints for sign-ups and data sharing. You will have full control over the technology stack on the .NET side, so feel free to suggest frameworks such as Giraffe, Saturn, SAFE Stack or any other F#-friendly tools that help us move quickly while keeping functional principles intact.
