About

Product-oriented fullstack developer, I work with business teams to build robust and maintainable applications. I pay close attention to accessibility, performance, and developer experience.

I enjoy contributing across the full lifecycle: discovery, technical design, frontend and backend implementation, then production delivery. My goal is to ship useful and scalable solutions with a clean codebase that supports collaboration over time.
