Backend Engineer building scalable microservices and real-time systems with Node.js and AWS.
IndiaWhat I'm looking for
I’m a Backend Engineer with 4+ years of experience building scalable microservices, real-time systems, and cloud-native architectures. I design high-performance REST APIs and event-driven platforms with strong system design, database optimization, CI/CD, and observability.
At Nliven Technologies Pvt Ltd, I built a real-time TV Bingo platform processing 1M+ bingo cards with a live number draw engine, supporting 5,000+ concurrent WebSocket connections and sub-100ms response time. I implemented Redis-based winner tracking and leaderboards, reducing database query load by 60%, and delivered secure onboarding via SafetyNet KYC verification.
Earlier, at Gyizer Systems, I developed modular REST APIs using LoopBack 4 with design patterns that reduced code duplication by ~40% and improved maintainability. I also optimized high-traffic endpoints and database queries, bringing average response time from 600ms to under 150ms, and at Cubexo I supported 10,000+ users with 15+ RESTful modules—cutting API error rates by 35% and speeding new feature development by 20%.
