I develop native Android and iOS applications of any complexity fast, skilfully and always on time. I graduated from a computer science faculty and have 3-year experience in mobile phone software development. I work for an international company. Freelancing means for me new interesting projects and an additional income. Software development is not only my profession, but a favourite hobby as well. I’m a perfectionist, therefore I strive to implement all tasks the most elegant way. In my assignments I also take care of the technical aspect of the application and I make recommendations. After development I will help to publish and subsequently support and further develop the application.
