About

I like clear requirements, sensible architecture, and incremental improvements. I use LLMs in my own workflow—experimenting with tooling, automation, and ways to ship faster without sacrificing quality.

I have been writing code since I was 15; I still enjoy tricky problems, side projects, and open source when there is something worth sharing.
