Summary
🤩
Rockstar🎓
Top SchoolSergey Semushin is a Senior Programmer with 13 years of experience, currently shipping C++ and game-adjacent systems at Playrix after a decade of engineering and Qt GUI work at Rock Flow Dynamics. He combines deep build-and-release expertise—evident from contributions to the hunter CMake-based dependency automation—with hands-on game-engine development and UI work seen in notable Diablo engine reimplementations (devilution and freeablo). Comfortable across back-end object management and front-end rendering/UX, Sergey repeatedly refactors and stabilizes complex codebases while integrating third‑party libraries and fixing platform build issues. Educated with a Master's in Computational Mathematics from MSU, he brings a strong algorithmic foundation to practical engineering problems and a knack for making legacy engines and build systems more maintainable.
