About Me

As a Full-Stack Developer, I build clean, fast, and intuitive web applications. I'm constantly exploring new technologies, honing my skills, and seeking smarter, more efficient ways to solve problems. I thrive in dynamic environments, quickly learning new tools and languages to adapt to any project need.

My toolkit revolves around JavaScript, TypeScript, Angular, and React, and I’ve spent the last few years building high-performance apps and leading Agile teams from idea to launch. I’m big on modular architecture, thoughtful design, and creating systems that grow gracefully.
