About the founder: I have graduated from Gdansk University of Technology, with masters degree in computer science. My professional experiences include work as a developer and a team leader in corporations: IFS in Poland and UK, Nokia in Berlin. I know several programming languages, I've worked on a variety of issues, in various teams and environments. Then I concentrated on designing and developing mobile applications. I was working alone for many years. Then I started to complete the team. All that has resulted in an offer that I present you with a clear conscience. All the details contained therein are practiced by us, applied in at least some successful projects.
Looking forward to doing business with you!
