04 / About

Backend-minded. Product-aware. Comfortable in the messy middle.

I enjoy working where application code meets real operational constraints: distributed services, unreliable dependencies, evolving requirements and data that cannot simply be thrown away.

My day-to-day work is rooted in .NET and SQL Server, while my side projects push me into React, TypeScript and AI. I care about systems that are understandable, observable and useful—not just systems that compile.
