Back to original languageAbout Clément
Having worked in embedded systems and especially video games 🎮 on projects like Microsoft Flight Simulator ✈, it's only natural that I've developed a fondness for software performance and optimization!
Today, as a co-founder of the company siliceum, I offer not only my services for performance audits and C++ expertise but also for video game engine development. My experience with various portages and "legacy" codebases allows me to adapt quickly.
I can therefore intervene for:
- Performance audits
- Development of your low-level and/or embedded applications
- Porting applications / games to new platforms
- Implementation of quality and performance best practices
- Video game engine development
- Scientific computing
- Training and C++ upgrades
