Led backend development for a Camunda-based dock assignment system integrated with warehouse management systems. Optimized truck routing algorithms, reducing wait time from 18 to 7 minutes for 200+ daily dock assignments. Replaced 6 PRI lines with SIP trunking and implemented 9 IVR flows, handling 400+ daily calls. Authored OSHA-integrated safety checklists improving compliance from 25 to 4 annual citations. Deployed ELK-based monitoring across distributed services with real-time dashboards, cutting DevOps MTTR from 4 hours to 72 minutes. Built Kafka Streams bridges linking Samsara and Motiv ELD systems (~15 msgs/s), enabling sub-second alerts for fleet management. Automated maintenance workflows by connecting odometer data to JIRA, reducing unscheduled repairs by 15%. Consolidated HOS logs and time-clock data, eliminating 30 person-hours/month of payroll entries. Created 6 real-time React/OAuth2 dashboards with WebSocket connections to boost dispatch visibility. Implemented Kafka-to-C

Led development of a Camunda-based dock assignment system integrated with the warehouse management system, optimized truck routing, and migrated 200+ legacy ESB services to cloud-native microservices. Executed 6 PRI-to-SIP migrations, implemented 9 IVR flows, and created real-time dashboards and alerting to improve dispatch efficiency and reliability, resulting in substantial reductions in wait times and operational SLA penalties.

Split monolithic iCard Issuance System into 80+ Java/OpenShift microservices to modernize the issuance platform. Built GitLab CI/CD pipelines with automated testing and deployment, cutting release cycles from 1 week to 1 day across 6 dev teams. Standardized JSON message formats across card processing services, reducing support overhead. Authored comprehensive system architecture documentation and API specifications, improving onboarding for new developers. Migrated 5,000 IBM ESB/MQ services to Java/Kafka microservices on OpenShift, eliminating vendor lock-in and improving reliability. Converted monolithic ESB flows to event-driven architecture using Apache Kafka, reducing downtime and accelerating feature delivery. Replaced DB2/Oracle databases with PostgreSQL for 15M+ daily transactions, collaborating with DBA teams for a seamless migration. Implemented OpenShift pod-warming strategies to eliminate cold starts, cutting application startup times by 70% across containerized services. Bu
