ASP.NET Jobs

I need a Windows-based desktop application written in C# that can connect directly to ours BK-280 BIOBASE Biochemistry Analyzer, MS-H655 Medical System and U500 Mission Expert laboratory equipment, pull each new result as it is produced, and store it in a local database. Beyond simple capture, the software must let authorised staff browse, search, edit or delete records so the instrument’s raw output is always available and manageable from one screen. Once a result is safely stored, a second requirement kicks in: the data has to be forwarded automatically through a Web Service (REST preferred, JSON payloads) to an existing web application. A simple status response confirming successful transmission will keep everything in sync. The web service must be hosted on our server with .NET ...

Our in-house team is mid-stream on an ASP.NET application and a row of stubborn bugs is slowing the release schedule. I need a fresh set of expert eyes to isolate the root causes, patch the issues cleanly, then push the fixes through our Git workflow so the build runs error-free. Scope • Review recent error logs, stack traces and user-reported glitches. • Reproduce each problem locally, document its origin and implement a solid fix in C# / ASP.NET Web Forms (the project also touches a few MVC pages). • Run regression tests, confirm nothing else breaks, then submit a pull request with clear commit notes. Acceptance criteria • No uncaught exceptions on the affected pages. • All automated tests pass and new tests cover the fixed edge cases. • Code a...

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. Therefore, you will 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 ...

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...
