About
A bit about me
Developer, problem-solver, and lifelong learner.
I'm a full-stack developer with a focus on building products that feel fast, intuitive, and thoughtfully designed. I enjoy turning complex problems into simple, elegant solutions.
Over the past few years I've worked across the stack — from React frontends and design systems to Node.js APIs and cloud deployments. I care deeply about code quality, accessibility, and mobile-first design.
I'm always looking for new challenges and opportunities to grow my skills. If you have any projects in mind, feel free to contact me!
