ABOUT ME
Senior UI Engineer & Front-End Developer
Senior UI Engineer & Front-End Developer
Full-stack engineer with 15+ years building products at early-stage startups, from founding engineer at Replo (YC S21) to leading technical projects across agencies and e-commerce companies. Strong focus on React, performance optimization, and headless architecture. I've taken projects from zero to production across many different technical domains and enjoy the fast-paced nature of startups where you need to wear multiple hats and take real ownership.
