Rockstar🎓
Top SchoolBorislav Stanimirov is a Staff Software Engineer with 14 years of deep C++ systems experience, currently working on medical device software and previously shaping AI inference and game engine technology. He blends low-level performance engineering (CUDA, GLSL, platform-specific build fixes) with cross-platform build and automation expertise (CMake, CPM.cmake), ensuring projects compile and run reliably across Windows, Linux and macOS. An active open-source contributor, he has improved high-profile projects in the ML and inference space—like ggml/llama.cpp and whisper.cpp—by fixing MSVC compatibility, adding GPU optimizations and refactoring core components. His background spans product-critical domains from cancer treatment systems to real-time game engines, giving him a practiced sense for robustness and architectural trade-offs. Comfortable both as a systems architect and hands-on implementer, he often surfaces subtle portability and build issues that others miss. He publishes code and writing at ibob.bg and maintains a focused GitHub presence highlighting pragmatic, cross-platform C++ engineering.
