At Tekion Corp, I engineered a Spring Boot and Kafka integration layer that standardized APIs across 50+ OEM/F&I vendors, reducing vendor onboarding time by 85% and enabling instant vendor switching for 3,000+ dealers.
I designed fault-tolerant AWS Step Functions and EventBridge workflows for the car-loan lifecycle, contributing to $750K in annual recurring revenue. I also built a distributed audit platform using Java, Kafka, Debezium, PostgreSQL, and AWS.
At Samsung, I optimized the EMS-2 release by resolving 45+ critical bugs and built the foundation of a supervisor reporting module. I also integrated the Total Solution Center with EMS, cutting average call handling time 9x and email reply time 4x.
