Engineered an asynchronous SQL to MongoDB data sync pipeline using Kafka and Airflow, reducing API latency and improving read scalability across decoupled services. Architected a real-time notification service using Kafka and WebSockets, eliminating client-side polling and minimizing delays in event-driven communications. Implemented 25+ high-throughput REST APIs across independent microservices using Spring Boot and JPA, enforcing JWT-based Spring Security for fine-grained role-based access control and maintaining sub-200ms median response times. Integrated Redis caching for high-volume APIs with optimized cache invalidation and query-level tuning, slashing database load by 60% and consistently achieving sub-50ms response times under concurrent traffic. Built an Orchestrator Service for large-scale data exports using Kafka for non-blocking processing, enabling dynamic field selection, Excel generation, S3-based file hosting, and automated email delivery workflows for enterprise users. Refactored heavy React components using memoization, virtualization, and code-splitting, trimming UI re-renders by 45% and elevating overall frontend performance. Delivered 40+ interactive Highcharts visualizations in React.js, boosting user engagement by 30%.
