Summary

Senior Frontend Engineer and Tech Lead with 9 years of production experience across React, Next.js, TypeScript, and large component systems, including 5 years leading remote teams for US, UK, EU, and AU clients. I build and govern design systems: at PrimeUI (primeui.com, launched Feb 2026) I built and maintain a library of more than 200 React components together with the design-system tooling and the pipeline that composes them into production pages. Earlier I architected a multi-tenant, white-label Sanity backend for Tipico US that handled 75M requests/month across core and state teams.
