.NET Jobs

Hi there, I need a full-stack developer, or team, to build a multi-tenant logistics management system built on Angular 14 for the front-end, .NET Core for the API layer, and SQL Server as the data store. The one capability that must be solid from day one is Fleet management—vehicles, routes, and operational data must stay completely segregated per tenant while sharing the same codebase and database. Everything has to scale cleanly as new companies sign up, so tenant isolation, role-based access, and configurable settings are essential parts of the architecture. Core scope • Set up the tenant-aware user authentication/authorization flow (JWT or similar) • Design the SQL Server schema with row-level or schema-level isolation to keep each tenant’s fleet data separate ...

I run a growing chain of bakeries and now need a single, cohesive system that lets every outlet bill customers, track stock and feed all figures back to a central server. Compatibility • The point-of-sale itself must be a Windows desktop application that works offline when needed, then syncs continuously with a web-based server for consolidated data and remote management. Core scope • Billing & Sales tracking – quick item lookup, discount handling and GST-ready printable / digital receipts. • Inventory – real-time stock level tracking at each outlet, automatic deduction when a sale is made, and a central view so I can reorder in time. • Reporting – daily, weekly and monthly sales reports broken down by outlet, item and GST slab. Export to...

I am building a green-field fraud-detection platform and need an experienced back-end engineer to own the server-side work for the next three months. The stack is .NET (C#), PostgreSQL, and Redis; a separate team will handle the React front end, so your focus stays firmly on the APIs, data layer, and real-time processing pipeline. What the engagement looks like You will translate our detection logic into clean, well-tested C# services, design the relational schema in PostgreSQL, and use Redis for low-latency caching and message queues. Because the app is completely standalone, there are no third-party or legacy integrations to worry about—every decision you make will directly shape the core product. Key expectations • Produce readable, documented code that passes automated...

I’m building a C# web application in ASP.NET Core and I’m looking for an experienced developer who can jump in and accelerate the remaining work. The project centres on three pillars: solid user authentication, clear and responsive data visualisation, and reliable third-party API integration. Where I am now: the solution skeleton and basic routing are in place, but the heavy lifting on identity management, charting dashboards, and the external API logic still has to be completed and wired together cleanly. What I need from you: • Implement secure registration, login, and role-based access using ASP.NET Core Identity (or another approach you recommend, as long as it stays within the framework). • Build interactive charts/graphs that pull data from my existing E...

We are building a large-scale membership and operations management platform designed to support an international organization with multiple offices in different countries. The system will allow users to register online, apply for membership, participate in events and activities, communicate with local offices, and manage their involvement in the organization. The platform must support thousands of members, multiple offices, and structured management roles while maintaining high security and scalability. This is not a simple CRUD website — it is a full operational platform. We are looking for an experienced .NET / Azure architect or senior developer to help design and potentially build the system. Architecture Direction The system will start as a Modular Monolith (v1...

I need a application that lets me tag every palm tree on the farm with its own QR code. The flow is straightforward: I enter a new tree, the program generates and prints a unique code, we fix the label in the field, and any time the code is scanned the system instantly pulls up that tree’s record so we can add or edit details—species, current growth notes, location in the plot, or any other data points we decide to track. The software must run smoothly on Windows 10 laptops and work offline, storing its data in a lightweight local database with an easy way to back up or sync when we have a connection. A clean, uncluttered interface with large buttons is essential because farm staff will be using it; think Electron, WPF, .NET, JavaFX or whatever desktop framework you prefer, as...

I’m spending far too much time re-typing purchase vouchers into Tally when everything is already organised in Excel. I need a small utility that reads those spreadsheets and posts each row as a purchase entry in my Tally company, with all taxes, supplier details and inventory lines carried over exactly as they appear in the sheet. You are free to choose the most efficient route—Tally XML import, ODBC, TDL, or a Python/.NET bridge—so long as the final result is a one-click (or near one-click) process that any non-technical staff member can run on a Windows machine. Deliverables • Executable tool or script with a simple UI or clear command-line instructions • Mapping configuration so I can point new spreadsheet layouts to the correct Tally fields without cod...

• Description The objective is to create a prototype that sends our XML string via AS4 to a destination URL. You can start with <test>dummy</test> for now, but we will test with real xml. You will need to sign with the internal private key certificate and encrypt with the external public key certificate. The other side will decrypt with their private key certificate and verify our signature with our public key certificate. We will give you the certificates. You will then listen to our URL. They will send an async message 10-15 minutes later. We will give you access to our VPS, so the DNS will be routed to the VPS. You will need to verify their signature with their public key and decrypt the message with our private key. Success metrics are that the message is successfull...

I have four Excel workbooks that I now need housed in an existing MS Access database. None of the sheets are relational at the moment, so the job is a straight import and structure clean-up rather than designing complex links. Here’s what I need from you: • Import 4 existing Excel Files into 4 tables in an existing MS Access DB (.ACCB) • Add a few basic queries so I can filter, sort and export the data quickly. • Delete bad data and duplicates The project is to be done in .net with WPF user interface. Once complete, send me the .accdb file and the brief how-to notes—that’s it. If something in the data suggests a better structure, feel free to flag it before you proceed; otherwise, a clean one-to-one migration is all I’m after.

We have a legacy Windows desktop application built on .NET Framework 4 that captures video from a USB webcam using and a custom wrapper WebCam_Capture.dll. The program works correctly on some machines but fails to recognize our Veho USB camera on others, even though the camera works in modern apps (Windows Camera app, browsers, online webcam testers). We need a freelancer to analyze, patch, and improve the camera handling logic so that the software consistently recognizes the camera across all machines. ⸻ Key Requirements / Skills: • Strong experience with .NET Framework 2.0–4.x and C# • Experience with DirectShow / video capture pipelines • Comfortable with Windows desktop apps (WinForms/WPF) • Experience with reverse engineering / decompiling .NET assem...

My WPF desktop app is halfway there; the core logic is working, but the presentation layer and final polish still need attention. I already have a detailed UI specification, so you can focus on bringing the remaining screens to life in XAML, wiring them cleanly into the MVVM structure, and making the whole thing run smoothly against a SQL Server back end. Here is what still needs doing: • Implement every control, style, animation, and layout exactly as shown in the spec. • Connect views to the existing SQL-driven data layer through well-structured ViewModels, keeping bindings clean and testable. • Profile memory, rendering, and startup behaviour, then eliminate the bottlenecks so large result sets scroll without stutter. I’ll hand over the current Visual Studio ...

I need a small Windows-only application that can take a folder of 20–100 TIFF files, apply a unique pixel shift and crop to each image, then save the processed set to disk. After that, the program should average the processed images into a single composite frame and finally assemble every frame into a short video clip. All parameters—image size, batch size, per-file pixel shift, crop dimensions, output frame rate and any other relevant image settings—must be editable from a clean, graphical interface that carries my company logo. No multilingual support is required, so the UI can stay in English. To speed things up I can supply an existing Lua script that demonstrates the core image calculations; feel free to translate or rewrite it in the language you are most comforta...
