About
Full-stack developer with 8 years of experience building web products for startups and growth-stage companies. I specialize in React, TypeScript, and Node.js — and care deeply about the intersection of engineering quality and user experience.
I've led frontend architecture for products serving 50K+ users, built design systems from scratch, and shipped production code across healthcare, fintech, and SaaS. Most effective when owning a feature end-to-end — from database schema to pixel-perfect UI.
