What I'm looking for

I’m looking for a product-minded team where I can lead frontend architecture, ship design-system-driven UI, improve developer experience, and make data-backed decisions across web and mobile.

I’m a product-minded Senior Frontend Engineer with 12 years of experience specializing in React, TypeScript, UI development, and Web Platform APIs. I lead technical strategy and cross-platform coordination across web, iOS, and Android—turning ambiguous requirements into systems that multiply team velocity.

I build design systems that make delivery dramatically faster, including a platform design system that reduced release time from weeks to days. I also drive backend-driven UI by leading a 1+ year initiative enabling dynamic flow creation without frontend deployments, alongside data-driven architecture decisions validated with A/B testing and analytics.

On the engineering side, I improve developer experience through CI quality automation, visual regression, Storybook, and Vite migration, while maintaining strong e2e coverage. I establish engineering standards with RFCs/ADRs, mentor teammates, and bridge frontend-backend-product alignment—especially where WebView integration and WebRTC/User Media API capabilities matter most.
