ASP.NET Jobs

I have a desktop application that was originally compiled in C#. Its only task that now needs attention is the SMS routine. At the moment the program calls a small, home-grown web service; I can share full documentation for that existing endpoint so you will immediately see the parameters and payload it expects. Here is the new goal: whenever the application sends a message it must instead post to Africastalking’s bulk messaging REST endpoint ( ). All other behaviour in the app should remain untouched. so you can focus purely on refactoring the SendSms() logic, wiring in the required headers, URL parameters, JSON body and authentication for Africastalking. Deliverables • Updated source files (or a self-contained class / DLL) that replace the current SMS method • A...

I have a couple of active web projects that need an experienced developer comfortable in both ASP.NET and PHP. Some modules are already live, others still sit in prototype form, so you may be writing fresh components one day and refactoring legacy code the next. Your day-to-day work will revolve around: • Implementing new features that slot cleanly into the existing architecture • Squashing bugs and tightening security in the older code paths • Writing clear, well-commented code and concise commit messages so future maintenance stays painless You’ll work in Git, commit to feature branches, and open pull requests for review. When you push an update, I’ll test it on a staging server and give feedback within 24 hours—rapid iterations matter to me. ...

The project involves building two tightly-coupled applications that share the same SQL Server back-end: • an ASP.NET-based web application for browser access, and • a Windows desktop client for on-site workstations. Both fronts must read from and write to the same database tables so users experience identical business logic and data integrity no matter where they sign in. Core requirement The system has to communicate in real time with a pharma instrument connected over USB/COM (exact protocol documentation will be provided). I will supply sample command sets and expected response frames; the software must initialize the device, capture measurement data, validate it, and commit the results to SQL. Typical workflow 1. User starts a test from either front-end. 2. The a...

I’m starting a new C# web project and need someone to spin up a clean, well-structured ASP.NET Core application focused on user authentication. The goal is to have a solid foundation that lets me plug in future features without having to revisit the sign-in logic later. Here’s what I need right now: • A fresh ASP.NET Core solution configured for Web API + Razor (or minimal API if you prefer) • Secure registration, login, logout, and password-reset flows backed by Entity Framework Core • Email confirmation and password recovery endpoints wired to a test SMTP provider (SendGrid sandbox or similar is fine) • Role or claim support so I can gate certain pages behind Admin or Member access later • Well-commented code, clean folder structure, and a ...

I need an experienced full-stack developer who can jump in immediately and spend the next two days (now through 19 April) pairing live with my small team. We already have a React front-end scaffold and a partially built ASP.NET Core back-end; your job is to connect the dots so everything works seamlessly. We are exposing a RESTful API and must complete three core capabilities before the deadline: user authentication, data retrieval, and data submission. On the front end you will wire these endpoints into React components that include real-time form validation and a handful of interactive UI elements. You should be comfortable shaping clean TypeScript props, handling state with hooks or Redux, and writing concise Axios (or Fetch) calls that respect our existing folder structure. For the b...

I’m expanding an e-commerce platform built in ASP.NET and need a developer who can stay with the project long term. The core work revolves around three pillars: solid user authentication, seamless payment integration, and reliable product catalog management. Where you’ll really make a difference is in automated document printing. Every order should trigger receipt, invoice, and shipping-label output without manual clicks, working smoothly across common browsers and printers. If you’ve already tackled auto-printing in web apps—handling silent printing, printer selection, and layout fine-tuning—you’ll feel right at home here. We iterate quickly, so clean, well-commented C#/ASP.NET code, Git familiarity, and clear communication are essential. Let me k...

I need a compact module that connects to my SQL Server database, fetches raw attendance data, and delivers a clean report that mirrors the sample layout I will share. Two filters must work flawlessly and in combination: date-wise and employee-wise—both hold equal weight for daily use. Any duplicate rows you encounter should be excluded before the data reaches the final grid or export. My preference is an ASP.NET / C# backend, though you’re free to craft the stored procedures as you see fit. Once the dataset is shaped, the user should be able to export the report to both Excel and PDF with a single click, keeping the exact formatting intact (headers, column order, totals, page breaks). Deliverables I expect: • A ready-to-run report with source code • Brief setup no...
