Rockstar🎓
Top SchoolClément Grégoire is a French C++ developer, co-founder and CEO with 11 years of experience specializing in performance engineering, game engines and constrained/real-time environments. He has a strong track record in the video game industry—contributing to Microsoft Flight Simulator and multiple console ports—and routinely tackles low-level latency, multi-threading race conditions and memory footprint reductions. As a consultant he has delivered measurable wins (e.g., cutting audio synth and embedded app load times dramatically, shaving milliseconds off frame times) and helped teams adopt profiling practices and tooling like Tracy. His open-source work includes accuracy and clock fixes for the widely used nanobench microbenchmark library and improvements to libctru for Nintendo 3DS, showing attention to both benchmarking correctness and platform internals. Comfortable bridging C++ with WASM, JS, Python and embedded stacks, he blends deep systems knowledge with front-end/webkit optimization experience. Based in Clermont-Ferrand, he pairs entrepreneurial leadership with hands-on technical problem solving across gaming, audio and embedded domains.
