01 / A little about meThe person behind the code
Curiosity at the core.
Purpose in every build.
I’m Arjun, a Computer Science undergraduate at Lovely Professional University. I build full-stack applications and developer tools, and practise data structures and algorithms.
From splitting everyday expenses to making development environments easier to set up, I like turning a practical problem into something you can actually use.
