From 2013 I am working on my own as a freelancer. During that time I have had three major clients with whom I have been running longer projects.

With Nomtek I have been developing big (over 40 different screens, over 30, highly linked REST resources' types) Android application for teachers in schools.

With Sygnity I have been running few projects (Android, responsive web app) for The Polish Post. Those included interesting aspects like digital signing the content, taking signature from users, tracking postman etc.

With Matchbox Mobile I have been collaborating for other 3 years on numerous projects for Android, iOS and Windows Phone / UWP platforms. I have been doing also very big research and comparision of mobile platforms (advantages, disadvantages, comparision to other platforms, problems etc.) - this was an internal project for one of the biggest Desktop & Mobile OS provider.

I have been running multiple projects on mobile platforms: Android, iOS, embedded Linux (set-top box) and Qt on desktop.

At TomTom I have been a Line Manager (though TomTom's internal term was: Team Lead) for group of ~12 internal developers and another group of ~20 extnernal contractors. I was responsible for people's motivation and undisturbed environemnt in Lodz, Poland office. I was running also employees' evaluations and was setting goals with every individual in my teams.

I was reporting directly to Netherland, Amsterdam office which was running my whole department from there.

I was subcontracted to Nokia from ComArch. For over two years I was onsite in Nokia Ruoholahti building in Helsinki, Finland.

I was working on future-then platforms for Nokia smartphones: Maemo and its successor MeeGo, both based on Linux. Maemo was based on C/Gnome environment, while MeeGo was much modern system, with UI based on C++ & Qt/QML frameworks.

I was responsible for architecture and development of one of the internal, system default application on Nokia N900 device. After intial phase (preparing architecture and discussions with other teams) client decided to increase headcount and hired 2 other developers from ComArch. I was leading that distributed team and, except development itself, I was also responsible for code reviews, bug triagging and general communication with the client. Our further work prompted Nokia to hire another developers from our company for other projects. I was then local line manager for all Maemo/MeeGo developers from ComArch in Nokia.

Most of the time I was subcontracted to Nokia and was developing software for theirs platforms Maemo and MeeGo. More about this here.

Except Nokia work, I have been running multiple other, internal projects for Maemo & MeeGo platforms. I was one of the creator of mDictionary project on Maemo.

I was running internal trainings for other developers and also code camps for local students. I was also one of the presenter on the first, official MeeGo conference in Dublin in 2010. I was presenting how pure C++ and Qt code can coopearate with QML components.

I have been also a supervisor for summer trainee groups with whom I have run many nice smaller projects. More than half of students from my groups had decided to stay and work for ComArch.

Just before Nokia's decision about switching to Windows Phone I was selected to be a manager for new "MeeGo Development" subcenter.
