I build and modernize high-impact full-stack products across AI, fintech, and commerce.
United StatesWhat I'm looking for
I've built and modernized full-stack products for Stealth AI, The Fitting Room, AWS, MoneyLion, Teachable, Hearst Autos, and enterprise clients including Chick-fil-A and E*TRADE.
At The Fitting Room, I owned end-to-end delivery of a React Native application, reducing load times from 10–30 seconds to under four seconds, and rebuilt the core dashboard with Next.js, TypeScript, and PostgreSQL. I’ve also built NestJS trading-platform services, Rust crypto and NFT applications, and Solidity smart contracts for DeFi automation.
I bring 19+ years of hands-on engineering experience, from modernizing legacy Java frontends at AWS to managing teams and shipping scalable commerce systems. Most recently, I built RL environments and evaluators to train LLMs on specialized industrial software workflows.
