Rockstar🎓
Top SchoolChris Ohk is an embedded software engineer and visiting senior researcher with 11 years of experience building real-time engines and cross-platform systems, from C++ game physics at Nexon to Rust-based interaction engines and embedded systems at 42dot. He has led technical direction and project specifications as a technical lead, and contributed to notable open-source projects in fluid simulation, reactive Rust, and Flutter–Rust bridging, improving code quality and API consistency. As founder of C++ Korea and a Microsoft MVP, he combines community leadership with hands-on implementation, frequently exploring reinforcement learning and voxel-based simulations in personal projects. Comfortable across C++, Rust, and low-level systems, he brings both product-focused delivery and deep engineering troubleshooting to research and industry settings.
