Orchestrated development of microservices ecosystem using NestJS, Express.js, FastAPI, Spring Boot, and PostgreSQL, implementing event-driven architecture that processed 500K+ daily transactions reliably. Developed custom authentication and authorization middleware with JWT, OAuth2, and TypeScript, reducing unauthorized access attempts by 95% and strengthening system security. Enhanced backend for Live Classes platform using AWS ECS, S3, CloudFront, MongoDB, Redis caching, and Docker, reducing response times from 5 seconds to under 1 second. Implemented real-time data synchronization with WebSockets, Socket.IO, Redis pub/sub, Webhooks, and Firebase integration, reducing data latency by 60% in distributed systems. Authored comprehensive Swagger API documentation and integrated CI/CD pipelines with GitHub Actions, Docker, and Kubernetes, significantly reducing new developer onboarding time.

Designed and delivered a live class service platform using NestJS, Socket.IO, WebSockets, React.js, and Angular.js, achieving 99.9% uptime and scaling to 10K+ concurrent users across B2B and B2C systems. Built a centralized communications service (COMMS) with FastAPI, MySQL, AWS Lambda, Redis, and SQS to reliably deliver Email, SMS, and Push notifications, and improve cross-team integration. Integrated Agora and Zoom SDKs with React.js components and implemented these SDKs in Angular applications for Admin, Teacher, and Student interfaces with real-time video streaming. Created an automated CRON service with Express.js, AWS Lambda, SQS, Puppeteer, and MongoDB, processing 10K+ daily tasks with 99.8% production reliability. Implemented event-driven architecture with Redis, MongoDB, SQS, and Firebase to reduce latency and improve fault tolerance across distributed services. Established monitoring and observability with New Relic, CloudWatch, and GitHub Actions, reducing downtime by 75% an
