Ported the main application to macOS and managed its App Store submission. Contributed to GPAC, a crossplatform multimedia project from Télécom-ParisTech. Presented the technology at SIGGRAPH 2014 in Vancouver, Canada, and at the MPEG-110 meeting in Strasbourg, France

Joined the early development of Space Hulk: Deathwing, working with Unreal Engine 4. Explored the engine independently, introduced its core concepts to the development team, and developed C++ and Blueprint prototypes for gameplay systems while helping establish the initial project structure.

Developed UI features for a web-based social gaming platform using PHP, Zend Framework, HTML and CSS, collaborating directly with the lead developer on interface design and player ranking.
