Backend Developer with hands-on experience building scalable systems across government, enterprise, and freelance projects — including a government-funded statewide transit system at IIT Kharagpur. What I've built: 1. Led end-to-end development of the Live Tracking Module at IIT Kharagpur — designed the Azure IoT Hub telemetry pipeline, built backend server and real-time tracking APIs, delivered the admin dashboard, and coordinated with the IoT hardware team. Sole owner from architecture to deployment, as part of a government-funded transit system for West Bengal & Odisha. 2. Built a Unified Grievance Management System for my college — multi-role hierarchy (Student → Teacher → HOD → Dept Admin → Super Admin), workflow-based approvals with SLA auto-escalation, real-time Socket.io notifications, and a full React operations dashboard. Node.js · Express · MongoDB · JWT · Zod. 3. Designed and deployed a Domain & Hosting Management Platform at Sharvin Management — reduced manual operations by ~60% and built an Australia Post live data scraper that made information retrieval ~70% faster. 4. Built real-time collaboration infrastructure using Socket.io and WebRTC — secure JWT + Google OAuth backend, modular async architecture improving server response time by ~40%.
