🎯 Backend Engineer | Node.js | System Design | Scalable Applications
I’m a self-taught programmer and a B.Tech in Computer Science Engineering (Chaudhary Charan Singh University) with 3+ years of experience building and scaling high-performance backend systems. I specialize in Node.js, WebSockets, MySQL, DevOps, and cloud-native architectures.
- Backend Development: Designed and scaled systems for millions of users and devices, optimizing for performance and reliability.
- System Architecture: Architected distributed systems, real-time communication servers, and IoT device middleware.
- DevOps & Cloud: Proficient in Docker, Kubernetes, AWS, and CI/CD pipelines for smooth deployments.
- Security & Optimization: Role-based access control, encryption, query optimization, sharding, caching (Redis), and race-condition handling.
- Full-Stack Development: Experience with React, Angular, and modern frontend tools to deliver end-to-end solutions.
- Attendance Middleware (AMS): Scaled to 10M+ employees and 1M+ devices, processing 3–4 API requests/sec/device.
- SmartListener: A WebSocket server handling 20,000+ concurrent users for IVR services using
uWebSockets.js+ Redis. - ANPR & Face Recognition Systems: Designed scalable backend architecture to process 20L+ enrolled images and high-throughput video analytics.
- Sales Analytics Platform: Designed data pipelines and dashboards for real-time analytics.
