Report

Hi, I'm Mateusz Ciszczoń, an all-around Full-Stack Developer with a creative and analytical mind that likes to solve complex problems in a neat and simple way.

There is nothing more rewarding and fulfilling for me than to have an opportunity to put all my skills in use in order to achieve the best possible results. I like my solutions to run tight, as creating anything slapdash makes me actually unhappy! I have a background in many different fields, having worked with graphic design and user interface, through front- and back-end development, to even music and sound design. I'm a deeply humanistic person, so I always try to have a bigger picture of whatever I'm dealing with.
