Full Stack Developer

Currently Software Engineer at BASU Education

I build things people can actually use. I’m a self-taught developer who learns by building and exploring new ideas. Outside of tech, I enjoy playing badminton and cricket, and I also love art — I’ve created a few paintings along the way.
