I'm a Senior Software Engineer with 7+ years of experience building reliable, production-grade web applications. My core is the .NET ecosystem — ASP.NET (Web Forms & Core), C#, and SQL Server — and I also build Python backends (Django, FastAPI), web scrapers, and Java/JSP web apps. I focus on clean architecture, secure authentication, and solid database design, taking projects from idea to deployment. Whether you need a web app, an API, web scraping, database work, or fixes to an existing project, I'll help you ship it right.

FAQ
I don't have the original developer anymore. Can you still work on my app?
Yes, that's exactly the kind of work I do. I regularly pick up existing Web Forms apps with no original developer around. As long as you can share the source code and database, I'll study how it works and take it from there.
My app is live in production. Is it safe for you to make changes?
Absolutely! I work carefully on live systems and never make reckless changes. I prefer to test on a staging copy first where possible, and I always explain what I'm changing before I do it.
I'm not sure what's wrong with my app. Can you help me figure it out?
Yes. Just send me a short description of the problem along with any error messages or screenshots, and I'll give you an honest assessment of what's involved before you order.
Which .NET versions and databases do you work with?
I work with ASP.NET Web Forms on the .NET Framework, C#, ADO.NET and Entity Framework, and SQL Server for the database. If you're unsure of your exact stack, I can help you identify it.
Can you eventually migrate my Web Forms app to a modern framework?
Yes, I can migrate Web Forms apps to ASP.NET Core / MVC when you're ready. It's usually best done as a planned project, message me with your app details and I'll advise on the right approach.
