Profile

What I bring to product teams

Frontend Engineer with 4+ years of experience building user-facing products with React and Next.js. I focus on shipping features that improve real user experience and business outcomes, not just clean code. I’ve worked across product teams, internal tools, and growth experiments, often owning features end-to-end while collaborating closely with design, product, and backend teams. My background in infrastructure and IT operations gives me strong systems thinking, while my product work has sharpened my attention to performance, usability, experimentation, and scalable frontend architecture.

Frontend specialist in React, Next.js, TypeScript, and scalable UI systems
Product-minded engineer comfortable across growth, experimentation, and internal tooling
Hands-on collaborator across design, product, backend, and customer-facing teams
Strong foundation in systems reliability from earlier infrastructure and IT leadership roles
