About Massessilia

As of June 2025, all companies marketing digital services in Europe must comply with the European Accessibility Act. And the majority are not yet compliant.

I can assist you in two ways: precisely identifying what's wrong (RGAA/WCAG accessibility audit, detailed report with a prioritized action plan), and designing or correcting your interfaces so they are compliant and pleasant for everyone to use (accessible UX/UI design).

Two years of experience at the Société des Grands Projets (Grand Paris Express) working on the intranet and internal tools for 1,300 employees. Complete design of an e-learning platform at Xifab.

Certified in Google UX Design, Microsoft Accessibility & Collaboration, Opquast (Web Quality).

My services:
→ EAA Flash Audit - quick compliance diagnosis (report + action plan), delivered within 5 days
→ Full RGAA/WCAG accessibility audit (detailed criterion-by-criterion report)
→ Accessible UX/UI interface design and redesign
→ Inclusive design system and ARIA documentation
→ Strategic support for EAA compliance
