I'm an MCA 2nd year student at COER University, Roorkee, building production-grade systems — not just tutorial projects.
I care about understanding what I ship: clean architecture, proper docs (PRDs, SDDs, threat models), and systems that actually hold up past the demo. Currently deep in DSA practice and building out a portfolio of backend-heavy, real-world tools ahead of placements.
Build. Break. Understand. Ship.
