Márk has worked as an Android Developer since 2014, taking part in both small and big projects. Both starting from scratch but also refactoring legacy code and code maintenance. Working in an agile environment (Scrum), following up with the latest Android trends (RxAndroid, DataBinding, Annotations, DI, Compose etc.). Very good experiences from working with continuous cooperation with test/server/IOS sides in different projects.
Experienced as independent worker but also as a member of a bigger team. Márk is very self-going, always strives for good quality and is a true team member. He sees the small details but don’t loose the big picture of the assignment.
