Turning specs into scalable systems — one commit at a time.
With over 9 years of experience in software development, I've collaborated with government agencies, global clients, and private enterprises to build scalable web and desktop applications. My expertise lies in C# .NET Core backend development, ASP.NET MVC/Web API, and modern JavaScript frontend technologies.
I'm passionate about writing clean, maintainable code and delivering high-impact solutions that streamline operations and boost performance. When I'm not coding, you'll find me exploring new technologies like ChatGPT API and Tekla Open API or mentoring fellow developers in their journey.
