Backend Developer with 2+ years building scalable NestJS/Node.js systems and high-performance APIs.
IndiaWhat I'm looking for
I’m a Backend Developer with 2+ years of hands-on experience designing scalable backend systems using NestJS, Node.js, Express.js, and MongoDB. I’ve built and optimized production-grade APIs for SaaS and B2B platforms, focusing on performance, security, and maintainable architecture.
Most recently, I managed a role-based SaaS task management backend, optimized dashboard queries to under 500ms through proper indexing, and integrated Cashfree Payment Gateway Subscriptions to support automated recurring billing and invoice generation. Earlier, at a B2B casino platform, I implemented multi-tenant support, JWT-based authentication, and a double-entry ledger system to ensure financial accuracy—then improved MongoDB query performance to sub-300ms and reduced API latency by 70%.
