ABOUT

I turn messy enterprise data into products people rely on — pipelines that run themselves, AI systems that answer real questions, and platforms that save thousands of hours.

3+ years shipping production data systems across construction, education and finance. I've re-engineered Palantir Foundry pipelines to cut compute costs in half, architected multi-LLM orchestration on GCP serving 500+ enterprise users, and owned full product lifecycles — from stakeholder requirements to deployed React/TypeScript applications.
