Goutam Kumar Sah

I’m a Senior Java Backend Engineer and Technical Lead with 8 years of experience designing, building, and operating scalable microservices for FinTech, government, and consumer marketplace platforms.

I specialize in Java 21 and Spring Boot 3, with REST API design, event-driven architecture, and data modeling in PostgreSQL/MySQL. I also work hands-on with AWS, Docker, Kubernetes, and Linux production operations, while keeping reliability and security at the center of every release.

I lead backend architecture and delivery—owning code reviews, release planning, and mentoring junior and mid-level engineers. I’ve designed production REST and reactive APIs (Spring WebFlux), integrated third-party financial and government APIs with retry/idempotency/reconciliation handling, and built event-driven pipelines with Kafka and RabbitMQ.

Across major projects, I’ve implemented caching and distributed session management with Redis, built real-time chat using WebSocket/STOMP, delivered multi-channel notification services, and performed security-hardening audits that resolved 24 defects. I’m especially motivated by end-to-end ownership—from architecture through production incident triage and delivery.
