Summary
🤩
Rockstar🎓
Top SchoolVojtech Bubnik is a researcher and seasoned software engineer based in Prague with over a decade of experience bridging academic research and production software in computer vision, 3D modeling, and embedded systems. He contributes to prominent open-source 3D printing projects such as PrusaSlicer and Prusa-Firmware, where his backend and firmware work improved G-code generation, support algorithms, extrusion precision, and compatibility with legacy toolchains. At Czech Technical University he combines PhD-level research in volumetric AR geometry with hands-on implementation of computer vision components for research projects. His background includes medical and industrial software architecture, NC machining simulation, and device firmware, giving him a rare cross-domain perspective from high-level algorithms down to low-level embedded optimizations. Known for pragmatic refactors and performance-minded fixes, he often focuses on subtle accuracy and interoperability issues that yield outsized improvements in real-world systems.
