I’m an iOS and Android expert who helps companies and startups design and develop mobile apps tailored to fit their users’ needs.

I have Master’s Degree in Information Technology (2007, Warsaw University of Technology) and I have been developing mobile applications since 2004 when I first started an internship as Windows Mobile Developer. In 2006 I began my work as a freelancer focusing on mobile app development (iOS, Android, Windows Phone). During my career, I have developed many successful applications and I’m continuously improving my knowledge and skills to keep up with the latest mobile development trends. My extensive experience with working on both large and small mobile development projects for different platforms, as well as my academic background, enables me to bring a full range of skills to the projects I'm being part of.
