AI RESEARCHER · PRODUCT BUILDER

I turn ambiguous technical problems into working systems.

AI research, real products, and a bias for action.

I like problems that don't have an obvious answer yet.
Research when needed. Build when possible. Ship what matters.

I'm Marek — principal engineer, AI researcher and product builder. I like working at the intersection of research, systems and real-world applications, especially when the path isn't clear yet. I write, build, experiment, and try to leave useful things behind.
