About
Engineering across the full stack
I'm a Full Stack Software Engineer with 3+ years of professional experience shipping production applications. I work comfortably across the frontend and backend — designing data models, building type-safe APIs, and crafting responsive, accessible interfaces.
My focus is on writing clean, maintainable code that scales. I enjoy turning complex business requirements into maintainable, scalable software, with a strong focus on clean architecture, performance, and developer experience.
