🚀 About Me

I’m a Backend-heavy Fullstack Software Engineer (4+ years) specializing in building scalable systems with C#, F#, .NET, MSSQL, and React. My work spans from AI-powered solutions to cloud-integrated healthcare platforms, always with a focus on delivering measurable business ROI.

I enjoy bridging the gap between technical depth and business impact, whether it’s cutting system latency, automating workflows, or building new product features from the ground up.
