I'm a senior software engineer from the Czech Republic with a master's in computer science and 8+ years of experience. My neural networks scanned 6+ million images in the fight against child abuse material, and my security research made national news.
At Boost.space I build on vector search and LLMs, develop the MCP server and work on the PHP/Nette API. After hours: model-level computer vision, training and inference, LLM and cybersecurity research.
