Backend engineer on delivery teams for a top US investment bank and a US insurance provider. Architected an AI-assisted test automation platform on Spring Boot and Python, splitting LLM test generation from deterministic validation so non-compiling tests never reached a human. 30% less manual QA effort and 40% higher platform throughput. Shipped LLM-powered Python microservices into live product workflows, with the model call behind a queue, circuit breakers and dead-letter queues, so a slow or failing model degrades one feature rather than stalling the workflow. Built Kafka producers and consumers with multi-threaded processing on high-volume trading data, and diagnosed a duplicate-delivery defect caused by exactly-once assumptions over at-least-once semantics. Spring Boot microservices on Kafka and RabbitMQ: API efficiency +45%, response payload -30%, database response time -35% through MongoDB index redesign and Redis distributed caching. Led Blue-Green deployments on Kubernetes with Jenkins CI/CD - zero-downtime releases and a 60% improvement in recovery time objective. 90%+ unit test coverage on critical service layers. Technical lead for backend feature delivery: requirement breakdown, estimation, and agile delivery across backend and frontend teams.
