About the Builder
Hi, I'm Rohit Siva Shankar
2nd Year Mathematics and Computing · IIT Guwahati
"I build systems that scale, tools that developers love, and products that actually get used."
About Me
I am a Mathematics and Computing student at IIT Guwahati who loves solving hard problems — both in algorithms and in real-world systems.
From competitive programming to full-stack development, I focus on building things that are not just functional, but scalable and clean.
CP sharpens thinking
Competitive programming trains me to find the optimal path under pressure.
Dev brings ideas to life
Full-stack development turns elegant solutions into real products people use.
