About Me

I'm a passionate developer with 4+ years of experience building web applications that users love. My journey started with a simple "Hello World" and evolved into architecting complex distributed systems.

When I'm not coding, you'll find me contributing to open source, writing technical articles, or exploring new technologies. I believe in continuous learning and sharing knowledge with the community.

Currently focused on building scalable applications with React, Next.js, and Node.js, while exploring the exciting world of AI and machine learning.
