Hi, I'm Pratim

Full-Stack Developer · Mumbai, India

Full-Stack Developer with 4+ years of experience building scalable frontend and backend systems. Experienced across React, Next.js, Node.js, NestJS, microservices, databases, Redis, AWS, and CI/CD. I enjoy working across the stack—from building products and APIs to deploying and scaling them in the cloud. Currently diving deeper into Kubernetes, distributed systems, and cloud-native infrastructure.
