01 / About

I'm a computer science and mathematics student at Case Western Reserve University who builds things at the intersection of quantitative systems, AI infrastructure, and startups.

Currently co-founding Darch AI, where I architect high-throughput media pipelines serving 20M+ monthly impressions. Previously built AI tools at NIST. On the side, I run automated trading systems on prediction markets — reaching the top 100 on Kalshi's all-time crypto leaderboard.
