About
I've been building Rails products for nine years. My recent work includes AI assistants, payment systems, and developer tooling.
Previously at Booqable, Roots Rental Software, and PayPro.
Selected work
- AI assistants
- Built Booqable's assistant for finding orders in plain language. Took it from beta to all customers, with permission-aware tools and streaming responses.
- Payments
- Rebuilt payment integrations around Stripe Connect, PayPal, and Mollie. Added Stripe Terminal and Tap to Pay. Before that, I worked on Adyen point-of-sale at Roots.
- Build tooling
- Moved CI from CircleCI to GitHub Actions. Builds went from over 40 minutes to about 12. Also replaced Webpack with Vite and rewrote the CoffeeScript in JavaScript.
