Welcome

About Me

Builder. Problem Solver. Full-Stack Engineer.

I'm a full-stack software developer with a passion for building performant, scalable web applications. With experience spanning frontend frameworks like React and Next.js to backend systems with Node.js, Java, and MongoDB, I bring a holistic approach to every project. I thrive on turning complex problems into elegant, user-friendly solutions and I'm always exploring emerging technologies - from AI-powered tooling to modern build systems - to stay at the cutting edge.

I love collaborating with teams that care about craft, and I bring both technical depth and a positive energy to every project I work on.
