   Led the design and scaling of the payment batch processing system to handle 2K+ payments per run by resolving distributed cache clustering issues, webclient timeouts, and JVM memory bottlenecks. Owned and drove performance optimization initiatives, reducing real-time screening latency by 93%(9.85s → 0.65s) through cache-first access patterns, multithreading, and search algorithm improvements. Designed and implemented a GenAI-powered keyword extraction workflow for variable-length narrative text, reducing analyst screening time from ~5 minutes to seconds. Built a local routing gateway(Helidon/Spring Boot/Frontend) for config-driven API routing between local & cluster services; adopted by 5 teams, cutting dev/testing cycles from hours to minutes. Served as interim technical lead for a 6-member team, mentoring engineers, driving design/code reviews, and leading feature and release demos.
