About
Product engineer with a good eye for clean, accessible interfaces and a real appetite for hard problems. Six years building products with teams — most recently real-time, high-stakes trading interfaces in DeFi using TypeScript, React, Next.js, and on-chain SDKs.
I owned Agent Pear, an AI trading-signals product, end to end, and was a core engineer on a Base mini app that brought on-chain pairs trading into Coinbase Wallet.

AI has changed how we engineers work, but hiring tests haven’t caught up. So I built one where candidates solve a real task with Claude Code, and recruiters get a score and a replay of how they got there.

Blur anything before you share your screen
I always wanted to share my screen without sharing my personal details. So I built an extension that blurs anything on the page and open-sourced it. Please fork and contribute!
