Back to original languageAbout Amen
Lead Developer / Senior Backend Developer with over 16 years of experience in Java-Spring environments. I am currently working at Boursorama on Middle applications, where I am leading various technical projects: load testing (Gatling Enterprise) and performance optimization, version migrations (Java 11 → 21, Spring Boot), legacy protocol migrations (pop3/imap → Microsoft MSGRAPH) and tooling (Nexus → JFrog), security foundation migration (Apache Shiro → Spring Security), as well as the electronic invoicing reform (Dispatcher EID project, Java 25 / Spring Boot 4). I also manage the run of environments (incident tracking, production deployments, configuration via Consul).
I am looking for a mission that will allow me to bring my know-how, my passion, and my resilience, and to be challenged functionally and technically on new topics and issues.
