// about

Who you would be working with.

I am a full stack engineer who takes products the whole way: architecture, backend, frontend, smart contracts, deploy, and the live domain.

My through line is autonomous agents and on chain payments. I have shipped agents that earn and spend real money over x402, a DeFi vault agent, a civic intake agent, and a Shopify app that competes on reliability.

Several of these were designed, built, and shipped under tight deadlines, then kept running 24/7 in production.
