Kálmán started to work at Prezi in 2011 as project manager and he filled several different position in the last few years: worked on the editor and on mobile apps as well. Nowadays he is the Director of Product and leads the Force cluster which is responsible for the Prezi Medium, Document Format, Rendering Engines, Infrastructure and Security.

Sometimes it’s hard for him to decide whether he is a Jedi or Sith because he tries to keep the balance of the Force. You can often find him playing guitar in the office’s kitchen or riding his foldable bike.

Before Prezi, Kálmán had spent 13 years at Novell in very different technical and management positions.
Additionally, he is an active member and contributor to several free and open source projects like Mozilla.
