A founder of a VR rhythm-games studio and a developer of EEG-driven cognitive games, he combines analytical rigor with creative, human-centered design that supports neurorehabilitation and storytelling via custom LLMs. At enterprise scale he led Big Data engineering teams and designed ETL frameworks for financial and postal systems, while today he focuses on ingesting millions of research papers for production-grade GenAI. Fluent in multiple languages and platforms, Marek is driven by the theoretical foundations of CS and an interest in agentic AI, making him equally at home architecting data systems or prototyping novel interaction mechanics.
