I'm Jeet — a Full Stack Developer based in Kolkata, India. I build end-to-end products from real-time IoT dashboards to multi-tenant CRM platforms that serve thousands of users.

My work at Cypheria AM Pvt. Ltd includes architecting a 29-server microservices system for an IoT platform and building a real estate CRM with dynamic multi-tenant databases.

I love the intersection of backend architecture and polished frontend — making things fast, reliable, and delightful to use.
