I build production Web3 trading systems, developer tools, and scalable product platforms.

At Trueo, I lead frontend architecture and build production Web3 and Uniswap trading systems, from a shared frontend monorepo to on-chain prediction-market infrastructure.

I designed and launched a Uniswap v4 contract stack and permissionless market launchpad on Base mainnet, remediating all eight High-severity and 14 of 15 Medium-severity audit findings.

I also built an AI-assisted delivery pipeline, expanded end-to-end testing from 7 to 29 specs, and improved pull-request review coverage from 70% to 90% while mentoring a junior engineer.

Previously, I led engineering at 17LIVE, where I built a self-service campaign platform that tripled monthly campaign output to about 150 and supported 15M+ monthly page views. Across Meta Rocket, 17LIVE, and game studios, I’ve worked hands-on across frontend, backend, smart contracts, games, and developer infrastructure.
