What I'm looking for

I'm open to remote senior backend and integration engineering roles where I can build resilient Java platforms, modernize enterprise integrations, and contribute hands-on to CI/CD and production operations.

I build and operate enterprise integration platforms for Newsan, connecting Oracle Fusion Cloud ERP, RabbitMQ, MySQL, warehouse systems, and ecommerce channels through 20+ Apache Camel and Spring Boot microservices.

I lead a squad of 7–8 engineers and own complex systems end to end, from functional analysis through production support. I've modernized 10+ business-critical integrations from RedHat Fuse 7.x to Camel 4, Java 21, and Spring Boot 3 without service interruption, and designed resumable saga patterns that recover multi-step ERP orchestrations automatically.

I've also operated Indeed's Jenkins CI/CD platform supporting roughly 40,000 repositories and thousands of daily builds, and built Java microservices for UScellular. I bring hands-on backend, integration, Kubernetes, and delivery-pipeline experience to senior remote engineering roles.
