At Oracle CAGBU, I delivered 15+ backend enhancements for Unified Designer’s TMF620/633/634 APIs, led TMF 634 v5 Conformance Certification, and built Kafka-driven lifecycle events that removed three direct REST dependencies. I also introduced Redis caching that reduced Oracle DB read load by 40% and automated Kubernetes deployments to accelerate releases by 60%.

Now at ACL Digital supporting Motorola Solutions, I re-engineer high-volume subscriber operations with Java multithreading and build production-like GridGain test environments. I bring five years of experience across Java, microservices, distributed systems, observability, CI/CD, and backend architecture.
