At MetLife, I embedded OpenAI GPT-4 and LangChain RAG pipelines into claims workflows, reducing manual adjuster review time by 35%. I also connected Kafka and Akka pipelines to process insurance events and cut end-to-end latency to under 80ms.

At Vidyardi Pvt Ltd (Client: Thermo Fisher Scientific), I built laboratory-data microservices with Spring Boot and Kubernetes and helped migrate 19 instrument-control endpoints from SOAP to REST. I also provisioned Azure infrastructure with Terraform and wrote TDD suites that reached 87% branch coverage.

At JPMorgan Chase, I developed APIs and React dashboards supporting financial workflows, and at MassMutual India I worked on policy-administration microservices and batch processing. I hold AWS Solutions Architect, Terraform Associate, and Oracle Java SE 11 Developer certifications.
