Back to original languageAbout Mustapha
Java/JEE Engineer with over 13 years of experience in developing complex enterprise applications. I started at GFI Offshore in Morocco, where I worked on Hybris e-commerce projects for La Poste and Conforama, then on backend systems for Bouygues Telecom and Orange Niger. Since 2017, I have been working at Atos/Worldline on payment and advertising platforms, where I progressed to the role of Technical Lead. My expertise covers the Spring ecosystem, microservices architectures, RabbitMQ messaging, and batch processing. Most recently, I've been integrating AI into my workflow with Gemini Code Assist to automate technical documentation.
