Front-End Developer | Senior Web Integrator with over 10 years of experience, I design performant, accessible, and maintainable web interfaces for large corporations as well as for product projects with complete autonomy.
What I concretely bring to my clients:
🔹 AtTotalEnergies(5 years), I designed dozens of accessible and reusable components within the group's Design System, withpixel-perfect fidelityto the Figma mockups provided by the UX/UI teams. I led the migration fromGulptoWebpack Encore**, bringing significant gains in build times and frontend asset management. I also maintained the technical documentation of the **styleguideusingMKDOCSto ensure component reusability by all teams.RGAAcompliance ensured across the entire site.
🔹 At Bouygues Telecom, I contributed to the redesign of the Customer Area within a high-stakes Agile team. Development of React components, integration of UX/UI mockups in HandleBars and React, and contribution to the internal Trilogy framework (fixes, evolutions) used by all group teams.
🔹 At La Centrale, I worked on a high-traffic website in the automotive sector (Promoneuve): complete graphic redesign, development of the vehicle comparator, implementation of LLD/LOA functionalities for professionals, and integration of the Appnexus advertising module.
My approach:
I don't just deliver code, I deliver sustainable solutions. Performance(Core Web Vitals)**, accessibility **(RGAA/WCAG)**, maintainability (strict TypeScript, unit and E2E tests) **and fluid collaborationwith UX/UI, product, and back-end teams.
