About Stephen

Unity C# Developer with 7 years of experience, I design and develop PC games and interactive applications from start to finish.
Founder of an independent game studio, I have gained comprehensive experience in the development cycle: software architecture, gameplay systems, performance optimization, UI/UX, and asset integration.
Accustomed to working independently, I handle both technical decisions and execution.
I am available for freelance remote missions on Unity/C# projects: PC games, 3D simulations, interactive prototypes, or feature integration on existing projects.
Based in Geneva, I work with clients in Switzerland, France, and across Europe.
