I've built institutional management portals and internal CRMs at Earth Services using the MERN stack, supporting thousands of active records. I created responsive React.js and Tailwind CSS dashboards that streamlined admissions and attendance workflows.
I design RESTful APIs, secure authentication with JWT and RBAC, and real-time dashboard updates with Socket.io. I've also integrated Razorpay webhooks for automated fee collection and payment-status reconciliation.
In Swiss Bank, I architected a banking platform with a double-entry ledger, ACID-compliant peer-to-peer transfers, pessimistic database locking, HTTP-only sessions, BCrypt hashing, and TOTP-based 2FA.
I've also built Kafka-driven railway microservices with Redis locks and Elasticsearch search, plus a WebRTC file-sharing platform that reduced transfer latency by 60%.
