BIO
I am a full-stack engineer who enjoys building clean, reliable web applications that solve real problems. I’ve led development on full projects—from designing the architecture to writing frontend and backend code—using tools like React, TypeScript, Node.js, and Supabase. At my current role in solar tech, I built a customer-facing portal that integrates authentication, project tracking, and third-party APIs. I care about writing code that’s both scalable and easy to work with.
