Full-stack engineer · New York, NY

Kevin Feng.

software engineer

I build full-stack systems where chess, software, and markets meet — coaching tools for classrooms, a platform for a 1,600-member chess club, and bots that trade prediction markets.

01 — About

Where chess meets code.

I'm a software engineer based in New York with a computer science degree from Hunter College and a long-running chess habit. Most of what I build lives somewhere between the two.

I keep the Marshall Chess Club running — one of the oldest chess clubs in the country. Its 1,600+ members register, renew, pay, and get tournament updates through a full-stack platform I maintain at 99% uptime. I also co-founded East Coast Chess, a tournament platform with real-time registration, Stripe payments, and live WebSocket pairings for competitive events up and down the coast.

On the side, I build things that trade. The latest is a fleet of 35+ Claude-powered bots on Kalshi's Bitcoin prediction markets — between the fleet and my own account, 7,399 trades at a 60% win rate. Same discipline as chess: calculate deep, trust your preparation, and never bet on hope.

Interlude — probability, in motion

You scroll, I sample.

Every few pixels of scroll drops a ball through the pegs. Each one is a cascade of coin flips — individually random, together a bell curve. It's the world my trading bots live in: thousands of small, probabilistic bets where the edge only shows up over the long run.

Always up for a good problem — full-stack, AI, chess tech, or markets. And I'll never turn down a game.
