Philosophy &
Research

I work with early-stage companies. The kind where you're either the first senior engineer or the only one. Architecture, code, infrastructure, production. I don't split work into "my area" and "someone else's area."

I've shipped in Angular, React, Vue, Node.js, NestJS, Express.js, Python. GCP, AWS, Cloudflare Workers. I pick what fits the problem, not what I'm most comfortable with.

"I'm also a PhD candidate in AI (NLP, LLM, RAG) and geospatial data. I started it because I kept hitting the same problem: the AI works in a demo, falls apart with real data. I wanted to understand why."
