Top SchoolArnaud Leray is an experienced web and AI architect with 13+ years at the intersection of generative AI, responsible digital design and front-end engineering. Currently leading IA Gén initiatives at Niji, he combines hands-on development with strategic choices of LLMs and tools (Cursor, Claude Code) to deliver accessible, eco-designed and secure code generation workflows. His portfolio spans large-scale Next.js/React and Vue.js projects, mobile apps in Flutter/Ionic, and immersive 3D/AR work in Unity—often with strict RGAA and OWASP constraints.

Based in Greater Rennes, he pairs deep technical breadth with a disciplined commitment to inclusivity, cost and environmental impact.
