I help startups and teams build reliable ASP. WebForms, ASP.NET MVC, ASP.NET Core, Angular, AWS, Azure applications, high-performance APIs, and scalable backend systems using C# and cloud infrastructure.
With 12+ years of experience, I focus on building systems that don’t just “run” - but stay stable, fast, and maintainable as your product grows.

Experience that matters
===================
• Built and scaled applications used by real users
