I am working on all sorts of things, but most of them have same denomintor - Brazilian jiu jitsu. Whether you'd like to support me for Grappling Challenge events, teaching and running our gyms (which are closed due to pandemic 8) or you enjoy our BJJ geekouts with Mikoláš Bílek (buy him a coffee too!). I am greatful for your coffees, they keep me going!
