Lead Frontend Angular Developer at CEGEDIM, building accessible interfaces and a reusable Storybook component library.

At CEGEDIM, I designed and developed high-performance, accessible interfaces for the Gers Platform project and created a reusable Storybook component library for group applications.

I integrated Claude AI and its agents into development workflows for code generation, refactoring, documentation, and complex bug resolution. I also used Figma, Claude Design, and MCP to connect AI with the design workflow.

At Akkodis chez Thales, I worked on MOUV RH, a national application for managing transfer and relocation requests. I developed Angular features, including a dynamic messaging module, and supported REST services and business logic with Java and Spring.

Earlier, I worked on TRIPO, MOOME, and EDUCAT across tourism, Agri-Tech, and online examinations. My work included web and mobile interfaces, REST APIs, database architecture, and a complex calculation algorithm for business data processing.
