I've built and operated production applications for Squire, a US payments platform processing over USD 1 billion annually, and OpenGov, whose contract management platform serves 2,000+ U.S. public agencies.
At Squire, I re-architected checkout around Node.js and Stripe webhooks, integrated Cash App Pay, and owned incident response to protect transaction integrity during peak periods.
I build across React, Node.js, TypeScript, PostgreSQL, and cloud infrastructure, and have also led blockchain gaming and a decentralized P2P marketplace using Solidity, Ethers.js, and MetaMask.
