Ingénieur Développement Web Full Stack & Data / IA — currently training at EFREI – Grande École du Numérique (Paris) and building production software as a Full Stack apprentice at PORT Designs.
Je suis une personne sérieuse, persévérante et rigoureuse, toujours en quête d'apprentissage. J'aime relever des défis et proposer des solutions efficaces et innovantes.
I'm a junior full stack developer who ships real software while training — currently re-engineering a production e-commerce platform at PORT Designs and running my own self-hosted, containerized infrastructure. I learn fast, ship carefully, and care about clean, maintainable code. Next step: Web Engineering apprentice at Thales (2026).
- Full Stack Web — React / Next.js on the front, PHP / Django / Node on the back. My main focus.
- Real production work — custom PrestaShop modules, overrides, a full migration, ongoing maintenance.
- DevOps, hands-on — Docker, Linux Debian server, Cloudflare, a self-hosted personal cloud.
- Data & AI — actively growing — Python, Pandas, chatbot integration; the area I'm investing in next.
Open To — junior / apprenticeship full stack roles, data-driven product work, and open-source collaboration.
