What I'm looking for

I'm looking to build high-performance, real-time product experiences where I can own frontend architecture, strengthen reliability and experimentation practices, and help teams deliver scalable, accessible software.

At Kyan/Premia, I build real-time financial interfaces that stay responsive under thousands of live rows, using Web Workers, Comlink, virtualization, event ordering, and shared accessibility-first components. I also own frontend routing, experimentation, feature flags, observability, payment flows, and Terraform-based multi-environment deployments.

Across Baubap, Belong Home, Eden, Runa, and Beepquest, I've led frontend teams, shipped React Native apps and healthcare platforms, migrated core products to TypeScript and Next.js SSR, improved bundle size by over 50%, and built reliable data and backend systems. I also solo-built Setto, a full-stack tournament management platform spanning web, mobile, APIs, caching, infrastructure, and E2E testing.
