About

Most ideas sound great until you have to build them. That’s the part I enjoy. I work on full stack web applications using React, Next.js, MERN, and modern web technologies, with a focus on building products that are simple, scalable, and easy to use. I care about clean code, smooth user experiences, and creating things that people genuinely enjoy using.
