Jakub has been diving since childhood, inspired by his father. He studied education at Charles University, specializing in biology and physical education — a solid foundation for teaching diving. Since 2012, he has been part of the Divesoft team, contributing to the development of diving computers and the CCR Liberty rebreather. Among his most remarkable dives are the discovery of a submerged Jewish cemetery and a descent into the world's deepest known underwater cave — Hranice Abyss.
