About Quentin

Senior Unity Developer and Computer Engineer, with over 8 years of experience in Unity and a decade of practice in video game development.

I work on video game and interactive application projects as a developer capable of handling the architecture, development, and delivery of complete solutions. My expertise covers gameplay, software architecture design, performance optimization, and cross-platform development (PC, mobile, VR, consoles).

I have worked on various projects ranging from independent video games to professional applications, including serious games for ENEDIS and projects for the Paléopolis museum, as well as game experiences, simulations, and interactive applications. I also participated in the development of a dating app (Datopia) and several complex Unity projects, including custom engines and architectures.

Accustomed to production constraints, I enjoy designing robust, scalable, and maintainable systems, while ensuring a good user experience and smooth feature execution.

I can act as technical support or lead on Unity projects, from prototype to production.

Feel free to contact me to discuss your project.
