Backend engineer specializing in scalable Node.js systems and real-time applications.
What I'm looking for
I am a Backend Engineer with 2+ years building distributed systems and full‑stack applications at India’s largest telecom, designing scalable architectures that serve millions with high availability and low latency. I specialize in Node.js, TypeScript, Express.js, REST/GraphQL APIs, microservices, database optimization, and real‑time systems such as WebSockets and WebRTC.
I have delivered platforms achieving 99.9% uptime and sub-200ms API responses, implemented Redis caching and query optimization to cut database load by 70%, built robust authentication (OAuth2, Keycloak, JWT) and CI/CD pipelines (Docker, Kubernetes, Azure Pipelines), and created real‑time collaborative applications using Socket.io and CRDTs. I focus on performance, reliability, and secure, maintainable engineering practices.
