I'm developing and maintaining NSI Luxembourg PSF's eCommodo application for Luxembourg government environmental authorizations, handling change requests, technical analysis, deployments, reviews, and ticket allocation when acting as Tech Lead. I've also contributed to WebSphere-to-Liberty migrations, including Java 21 and Jakarta EE 10 transitions.

Previously, I built an AI image-recognition feature for OPTICOD's OPTIWMS and delivered a tested, documented solution optimized for Android. My experience also includes Vue/Java, Angular/.NET/SQL, and PHP applications at CTG Luxembourg PSF, Caisse d'Epargne Grand Est Europe, and Mars Wrigley.
