I’m a Senior Backend Engineer with 3+ years designing scalable, high-performance distributed systems across fintech, insurance, and real-time collaboration platforms. I specialize in Java, Spring Boot, microservices, and event-driven architecture, with a strong focus on cloud-native, fault-tolerant services.

In contract roles at Paypal and Metlife, I’ve engineered and redesigned backend workflows for regulated industries—building idempotent charge handling, multi-currency refund logic, and secure insurance transaction processing. I also lead Agile delivery cycles, mentor junior engineers, and strengthen reliability through retry policies, circuit breakers, observability, and strict compliance standards like PCI-DSS and GDPR.

Earlier, at CodeHimalaya, I architected a microservices backend for cross-border remittance using domain-driven design and distributed guarantees (including exactly-once processing). I optimized caching strategies (Redis) to reduce latency by 40% and improved infrastructure efficiency to cut operational costs by 20%, while modernizing monoliths into microservices with real-time event processing (Kafka/MQTT) and centralized logging.
