Background
I am a Mathematics and Computing student at IIT Guwahati who loves solving hard problems — both in algorithms and in real-world systems. Competitive programming sharpens my thinking ✕, while development brings ideas to life ⚙. I founded CodeSmash to build tools that developers actually use every day.
