About me
Software engineer with 10+ years of experience building web-based products, working primarily around the frontend. I focus on structure, reliability, and long-term maintainability, with a strong sense for how systems behave in real use.
My work emphasizes UI and UX quality—clear interfaces, predictable interactions, and performance that supports usability—supported by experience across the stack. Alongside client work, I develop and evolve a side project focused on supporting structured drumming practice sessions, taking responsibility for product design, implementation, and iteration.
