At Zeta, I own and maintain a PostgreSQL-backed, Apache Flink-powered ACH processing platform that handles millions of transfers and NACHA file generation for merchant settlements. I reduced p99 cold-start latency from 10 seconds to 300ms by improving connection reuse, JVM warm-up, and asynchronous execution.
Previously at ZopSmart, I built event-driven Spring Boot workflows across 20+ microservices, improved transaction endpoint latency by 50%, and created CI/CD validation pipelines that reduced deployment rollback rates by 70%. I also build practical AI tooling, including an incident investigation assistant that uses RAG to analyze logs, metrics, runbooks, and historical incidents.
