Théo Chevalier

Localization Project Manager, Advocacy


I work in the Advocacy team at the Foundation, as a Localization Project Manager. More specifically, I help the team launch upcoming campaigns in multiple languages, taking advocacy specificities into account. I’m passionate about localization and do my best to help Mozilla have the biggest impact towards a healthier internet.

Before joining the Advocacy team, I’ve been a Localization Engineering Intern with the l10n-drivers team, from 2014 to 2016. I worked on different aspects of localization (project management, tools engineering, community building, QA…), thanks to the experience of my mentors Pascal Chevrel and Delphine Lebédel.

On my spare time, I contribute to mozFr as French localizer for products and websites. I also train newcomers and review various French L10N content (promotional material, blog posts, videos, etc.).

Reach out to me if you’re interested in translating Mozilla projects in French or translating Advocacy campaigns in your language!
