I'm a final-year CSE student at NIT Arunachal Pradesh. I like building things people actually use, and making sure they keep working once they're live.

🏔️ Campus Connect · live ↗
Our hostels sit ~100 m uphill from the market, so vendors had to climb once for every single order. Campus Connect groups orders into time slots so a vendor makes one trip for many orders, with OTP-verified delivery.
- Handles up to 500 orders/min without duplicate or lost orders
- Fast lookups (under 50 ms) and live notifications for students and vendors
- Self-hosted with full monitoring and alerts
