About

I'm a final-year Computer Science student at UPES Dehradun (graduating 2026) who enjoys building backend systems that are fast, reliable, and built to scale. Most of my work lives on the backend — designing REST APIs, handling auth (JWT with refresh-token rotation, OTP login), and using Redis for caching, sessions, rate limiting, and background job queues. I also work across the MERN and Next.js stack, so I can take a feature from database to UI. A few things I've built and shipped: • CoreAPI — a production-pattern REST backend with full auth lifecycle, Redis caching, and BullMQ background jobs • Interact — a full-stack social platform with real-time messaging (Socket.io), 30+ REST endpoints, and role-based access control • At Aispire — backend services for a cross-platform Electron desktop app, plus cutting cold-start delays by migrating deployment to DigitalOcean • At BioPay — a Java SDK-validation framework to test palm-vein auth hardware before the UI existed, de-risking integration Currently open to SDE / backend / full-stack roles (internship or full-time) starting mid-2026 — ideally in Bengaluru. 📫 vanshsrivastava709@gmail.com
