About Thibault

Software engineer with over 8 years of experience in complex mobile application development, specializing in the Android ecosystem, with expertise in Kotlin and extensive practice in Clean Architecture across multiple projects. My experience at Capgemini allowed me to work for prestigious clients such as Stellantis, Groupe Renault-Nissan-Mitsubishi, Vinci Construction, Carrefour Group... I participated in international-scale projects, where I contributed to the creation of robust and scalable solutions in complex environments.

Among my key achievements:

MyMarque: Contribution to the development of the mobile application redesign for PSA (now Stellantis), used by millions of users worldwide to manage their vehicles. I worked on migrating the application to a modular architecture (Clean Architecture) in Kotlin, thereby improving its maintainability and performance.

SPACE: Development of key features for remote vehicle control in the new Stellantis mobile application, resulting from the PSA-FCA merger. Working within the Remote Feature Team, I contributed to the integration of remote control functionalities, using Kotlin and Jetpack Compose, while collaborating with teams spread across multiple continents (USA, India, Europe, Asia).

Previous projects: as a developer at Capgemini, I contributed to various projects such as the intranet for Vinci Construction for the Cairo metro, the international intranet for the Carrefour Group, and the improvement of the mobile application for the Ministry of Social Affairs and Health, dedicated to managing death certificates and a few others.
