Tech: Java, Spring Boot, Kafka, Redis, Docker, AWS EC2, GitHub Actions
- Built 5 Spring Boot microservices behind an API Gateway with JWT validation and
X-User-Idheader injection - Prevented race conditions using pessimistic locking (
SELECT FOR UPDATE) + idempotency keys to eliminate duplicate payments - Kafka async notification fan-out; Resilience4j Circuit Breaker prevents cascading failures
- Redis caching (5-min TTL) on wallet balance and user details; each service owns an isolated MySQL DB
- GitHub Actions CI/CD — parallel builds, commit-SHA Docker image tags for rollback; deployed on AWS EC2
Tech: Java, Spring Boot, Kafka, Redis, Docker, WebSockets
- Handles 1,000+ concurrent users with 0% error rate and <100ms latency — validated via Apache JMeter
- Redis atomic counters for inventory management preventing race conditions
- Kafka Producer–Consumer decouples order processing, reducing API response time by 90%
- Bucket4j rate limiting + WebSockets for real-time inventory updates to connected clients
June 2024 – September 2024 | Siliguri, West Bengal
- Optimized complex SQL queries, reducing data retrieval latency by 40% for operations reporting modules
- Integrated backend REST APIs across multiple frontend modules
- Built responsive web interfaces using React, HTML, CSS, and JavaScript
