At Worldline, I build and enhance Java microservices that process and secure high-volume financial authentication data.
I've managed EMV 3D Secure transaction flows and automated scheduling loaders, reducing processing time by 50%. I also reduced manual deployment effort by 80% through GitLab CI/CD automation and reliable artifact-flow management.
I architected an EMV 3D Secure ACS and Telemetry Engine with Spring Boot, Spring Cloud, Spring Security, Angular, and WebSockets, supporting sub-100ms latency and 99.9% uptime. I use Generative AI and prompt engineering to accelerate root cause analysis and legacy code refactoring.
