I build high-scale React platforms, improving performance, reliability, and release safety.

At Delivery Hero, I build React and TypeScript self-service experiences—including help center, chat, and inbox—for roughly 32M weekly sessions across 10 brands, 65 countries, and 41 locales. I created a canary release process that reduced release blast radius by about 90% and helped cut global p90 FCP from 8.2s to 4.3s.

Previously at simplesurance, I led a frontend team delivering customer-facing applications, including a white-label insurance product and an SSR storefront integration deployed on 200+ e-commerce sites. I also improved test coverage and mentored junior engineers on architecture and code quality.
