Summary
Product engineer in New York. Freelancing solo since 2013. Give me a real bug with the time to dig and I’ll ship the fix. 45 PRs merged upstream to Expo, Convex, Bun, shadcn/ui, and others, every one came from hitting a wall in my own apps and chasing it down.

- 2018 to 2021 at This Is Not Art: built and maintained a custom Shopify storefront (Liquid) with anti-bot protections (velocity detection, duplicate-order blocking, URL gating) years before Shopify shipped native mitigation.

- 2013 to 2017 at Software Automation Services: designed and operated automation and monitoring infrastructure for the e-commerce sector, with hands-on application security research and API reverse-engineering. Shipped Python and JavaScript tooling, Chrome extensions, and related web services.
