Hi there, I'm
Tanmoy
Senior Software Engineer | Owning End-to-End Product Architecture & Cloud-Native Systems
Profile Summary
Senior Software Engineer with 7+ years of experience owning and delivering production systems end to end—from API design to cloud deployment and long-term maintenance. I focus on cloud-native systems using TypeScript, NestJS, and PostgreSQL, with strong full-stack experience in React and React Native when needed.
I have led architecture decisions, built reliable microservices, and created CI/CD pipelines that improved deployment speed, system reliability, and long-term maintainability. I work best in product-driven teams where engineers own systems, make clear trade-offs, and are accountable for what runs in production.
