AJTY is a Czech company with a branch in Canada focusing on mobile development, mainly iOS and Android. We work for both Czech and international clients (mostly Canadian). We implement our own projects as well, for example QR Platba or NOTIFIT. Besides mobile applications, we are very active in the field of 3D printing - we organise courses for the public where we teach 3D printing and let the participants build their own RepRap 3D printer (RebeliX model). You can find more information at tiskni3d.ajty.cz. We also take part in the instruction of 3D printing at the Faculty of Information Technology, Czech Technical University in Prague. Our team consists of students and graduates from the Faculty of Information Technology, Czech Technical University in Prague and we offer cooperation on interesting Czech and international projects.
