Who am I


I’m an iOS and Android consultant 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’ve been developing mobile applications since 2004 when I first started an internship in Psiloc - Mobile Development Company. In 2006 I started my work as freelancer as Windows Mobile developer and after few years I expanded my services to modern iOS and Android systems. Since then I developed many successful applications and I’m constantly improving my knowledge and skills to keep up with the latest mobile development trends.

Recent Projects


I was already convinced to work with Mat based on the experiences with BarTune. He drives to deliver a solution that not only meets the technical requirements but also comes up with suggestions and advises to improve user experience and quality of the applications. He had some difficulties with project scheduling, but we managed to work through them. Another important thing is that Mat is reacting fast in case an issue arises. He is very accessible, and his support in the event of an emergency is great.

We needed our BarTune app available for Windows Phone platform and found Mat trough one of the freelancing sites. He quickly delivered the app and later we worked with him on new features for our iOS and Android versions. Mat provides high-quality work, delivers as promised and it's easy to communicate with. I also like his pro-active involvement. Value for money!

It has been a pleasure working with Mat. He has helped us develop our first app version for Windows Mobile and then upgraded the app to a new platform. He has been very professional and very clear in all communications, which I appreciate. A solid addition to our team.
