I build resilient Java backend services and Kafka integrations that improve production delivery.

At Infosys, I deliver Java, Spring Boot, Kafka, and MongoDB services across four production runtimes. I built a bi-directional REST–Kafka bridge for 15+ integrations and resilience features that reduced duplicate traffic by up to 95%.

Previously at Deloitte USI, I optimized Spring Boot REST APIs to reduce latency by about 30%, increased test coverage by about 60%, and resolved 50+ critical production bugs.
