01 / ABOUT

Code that solves problems. Products that work.

I’m Prashant Singh, a Computer Engineering student at Graphic Era Hill University and a full-stack developer interested in backend systems, practical web applications, and AI-powered tools.

I enjoy turning ideas into usable products—from accommodation booking workflows to AI interview practice—and strengthening them with data structures, algorithms, and clean implementation.
