About

I make teams ship
better — and faster.

When I'm not building products, I'm designing AI-augmented development workflows, contributing to open source, and automating everything I possibly can.

I'm a Lead Frontend Engineer with 8+ years building high-traffic web platforms — from startup MVPs to enterprise-grade B2B e-commerce serving multiple markets. I specialize in Next.js App Router architecture, enterprise authentication, and platform migrations at monorepo scale.

Currently leading ~10 frontend engineers across two parallel tracks on a TypeScript monorepo, where I drove a 20% page-load improvement, scaled test coverage to 4,500+ tests, and pioneered an agentic AI workflow that cut ticket closure time by ~35%.
