About

Founder and engineer. 25+ years in payments, infrastructure, and security at Venmo, Meta, Mysten Labs, and Etsy.

Now co-founder of Quirence AI, writing production code daily on two products for teams building with AI agents. Rinkata gives a team and its agents one source of truth for goals, specs, and decisions. It launched on Product Hunt on September 30, 2026. Pressure puts agents from different labs on opposite sides of a question and has them argue it out before you commit.

Previously ran security software at Mysten Labs, led blockchain teams at Meta, and built Etsy's checkout. Work history is on LinkedIn.

Languages of choice: Python for ML, TypeScript for web, Rust when performance matters.

Data scientist at heart. Usually deep in whatever database technology is having a moment.

Ran the Tokyo Marathon on March 1, 2026 in 4:36:28, raising money for blood cancer research with Blood Cancer United. Race recap.

When not training for the next race, on my PC with the latest games, usually spending more time in the GPU settings and Ollama than in the game.
