SUMMARY
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,
will enable me to bring a full range of skills to the position advertised.
OBJECTIVES
In my work, I mainly focus on User Experience, compelling UI Design, and good Code Quality.
These three aspects help me create software which best serves user needs and is easy to
maintain in the future. Additionally, to increase my productivity I adapted Pomodoro and
Getting Things Done techniques, and I constantly try to learn new Xcode and Visual Studio tricks
which help me develop solid code in less time. My intermediate graphic design skills help me
perform graphics editing tasks whiteout the need of designer help – this is particularly useful
when the customer wants to test few ideas quickly without much effort.
Currently, I’m looking to find some new exciting projects to work on as iOS Developer. I have big
experience with working for various companies remotely and would like to be a part of your
project.
