Architected and deployed a production microservices-based Java backend using Spring Boot, Spring MVC, and Spring Data JPA / Hibernate with PostgreSQL as the primary relational database; designed and optimized complex SQL queries with strategic indexing, reducing average query response time from ∼600 ms to ∼200 ms (∼66% improvement).

Integrated Spring

Kafka to implement asynchronous event-driven data pipelines, fully decoupling notification and mail delivery from core business logic; deployed Redis via Spring Data Redis with a Cache-Aside Invalidation strategy, eliminating stale-data reads and sustaining sub-200 ms cache-served response times at scale. Containerized the full Spring Boot microservices stack with Docker, maintained CI/CD pipelines via GitHub Actions for independent service deployments on AWS EC2 behind an Nginx reverse proxy.

• Developed 12+ production Spring Boot REST API endpoints for real-time IoT sensor data ingestion, device control, and automated backend processing via Spring MVC, serving concurrent hardware clients.
• Reduced API response latency by 50% (400 ms → 200 ms) through MySQL query optimization, strategic indexing, and Spring Cache-based request-level caching via @Cacheable / @CacheEvict annotations.
• Architected a fault-tolerant Spring Integration MQTT publish-subscribe pipeline across 10+ sensor types, sustaining 99.9% message delivery under continuous load testing.
• Implemented Spring Validation (Bean Validation / JSR-380) and structured global exception handling via @ControllerAdvice / @ExceptionHandler, cutting invalid-payload failures by 90% and unifying telemetry into a live dashboard tracking 5,000+ daily sensor events.
