I build backend systems that stay correct under concurrency and load.
Java, Spring Boot, microservices, Kafka, Kubernetes — currently shipping production services at Bajaj Finserv Health.
- Backend APIs with Spring Boot / Spring Security — auth, RBAC, transactional correctness
- Concurrency-safe data access (optimistic locking, @Transactional boundaries)- Distributed systems: Kafka, Redis, caching, observability (OpenTelemetry)
- Cloud/infra: Docker, Kubernetes, AWS
MediConnect — production healthcare management API. Spring Boot 3.x + Java 17, Spring Security + JWT + RBAC. Thread-safe appointment scheduling via optimistic locking (@Version) to eliminate race conditions under concurrent load.
