Previously contributed to backend-scale initiatives, API optimization, and platform reliability. Led efforts around real-time data handling, database migrations, and microservice consolidation to improve performance and scalability.

Current role focusing on backend platform optimization, real-time data features, and microservices. Implemented real-time data fetch with Socket.IO and RabbitMQ, migrated from Firebase to PostgreSQL, reduced latency through code and DB tuning, refactored legacy JavaScript to TypeScript, and built a monitoring stack with Prometheus, Grafana, and Alertmanager. Contributed to architecture simplification to cut costs and improve maintainability.

Architected a high-performance microservice from scratch to handle high volume daily API calls (bets). Migrated multiple microservices from JavaScript to TypeScript to improve maintainability. Built a realtime service from scratch using Redis, RabbitMQ, and Socket.io to deliver live updates. Optimized database tables with proper indexing, reducing average API latency to under 50ms. Integrated the full stack into CI/CD, increasing deployment frequency from weekly to daily. Led a cross-functional team across backend, frontend, and DevOps. Built a CRM email sending system sending personalized emails based on daily user behavior. Built a full monitoring system using Prometheus, Grafana, and Alertmanager and pgHero. Implemented encrypted secret backups across regions for recovery. Dockerized microservices and deployed on GCP Kubernetes.
