Sebastien Feser
Game Engineer & Project Lead
I build game engines, ship polished gameplay, and lead teams to deliver. From low-level C++ optimization to Unity prototypes, I turn technical challenges into smooth player experiences. AI-augmented workflow, human-driven quality.
I don't just make games. I engineer the systems that make them possible.
