About Me

I am a self-taught full-stack developer with a strong foundation in Electronics and Communication Engineering. After learning modern web technologies on my own, I moved directly into real, production-level projects, gaining hands-on experience with Django, React, Next.js, Node.js, and Tailwind CSS.

I adapt quickly, learn fast, and contribute meaningful solutions that improve workflows and streamline processes. I enjoy solving real problems, taking initiative, and making a positive impact on both the product and the team.
