Project details
You will get a professional .NET developer with over 12 years of experience, focused on building reliable business applications, APIs, and backend systems, not just simple websites.
I specialize in ASP.NET Core, Legacy systems, C#, REST APIs, Blazor and Azure-ready architectures. Whether you need bug fixing, feature development, integration, or a complete application, I write clean, maintainable and scalable code that works in production.
My goal is not only to make the feature work, but to make it stable, secure and future-proof so your project can grow without constant rewrites.
I communicate clearly, suggest better approaches when needed, and keep you updated during development to avoid surprises.
If you're looking for a serious developer who understands real business software, you are in the right place.

Enhance ASP.NET Core Blazor App with API, Scraping, Reporting, and MSSQL Improvements
Umar was an excellent hire for our .NET development needs. He wasn't just a coder; he was a true problem-solver. When we hit a tricky spot with the API integration, he debugged it efficiently and got us back on track. His communication was clear and consistent throughout the project. It’s rare to find a developer with this combination of technical expertise and soft skills. Thanks, Umar!
