Principal Software Engineer @ Flychain
About
Philosopher and former product manager turned full-stack software engineer, with experience owning and shipping production systems using Python, JavaScript/TypeScript, Rust, C++, SQL, and more. I’ve built products from scratch, scaled quickly with lean teams, and helped shape architecture, strategy, and implementation. I thrive in early-stage environments where the work is messy, the stakes are high, and execution matters. I like building useful things with good people. The rest is negotiable.
