Saurabh Chaudhary

I’m a Backend Engineer specializing in high-throughput Node.js APIs and AWS infrastructure, focused on reliability and automation. I’ve designed systems that serve 10K+ concurrent users with 99.9% uptime, and I’ve improved delivery speed by cutting deployment cycles by 70% while reducing manual workloads by 40% through intelligent automation.

I enjoy owning the backend lifecycle end-to-end—architecture decisions, CI/CD pipelines, and production monitoring. In practice, that means building microservices and event-driven designs, delivering secure REST APIs with JWT authentication and role-based access control, and improving performance with Redis caching, query optimization, and connection pooling.

I also care deeply about correctness and compliance, including GDPR-compliant data pipelines that reduced data integrity errors by 25%. Outside core work, I’ve built projects like a distributed task queue with retry/dead-letter handling and a WebSockets-based real-time notification service for 500+ concurrent users—always with resilience, throughput, and operational readiness in mind.
