Summary
🤩
Rockstar🎓
Top SchoolOndřej Jamriška is a founder and seasoned software engineer with 11 years of experience blending research-grade computer vision and high-performance systems engineering. Based in Prague, he moved from a decade as a research scientist at Czech Technical University to founding EbSynth, applying deep technical skills to practical imaging tools. His open-source work shows strong low-level optimization expertise—rewriting CUDA kernels, adding CPU backends and polishing passes for fast example-based style transfer—and a rare full-stack shader and cross-language fluency demonstrated in a multi-language color-mixing library. Ondřej combines academic rigor with product-minded execution, able to turn complex algorithms into efficient, cross-platform implementations.
