Jakub Z.

We hired jzawadzki again after his first project for us - because he's just so damn good! We've skipped plenty of weeks of development thanks to his fast and efficient coding skills. In addition, he's great at communication and you quickly develop a partnership of mutual trust and sparring. You need to hire this guy!

jzawadzki is by far the best freelancer we've encountered so far! His skills in coding up an effective Wireshark dissector was fully matched by his attention to detail in doing so. We had minimal efforts throughout and got everything we asked for and more. Can highly recommend jzawadzki to all in here!

Again Jakub did a great job and worked within the ambiguity that comes with not quite knowing the end result. I have used him a couple of times and both times he has delivered above and beyond the initial scope. Very, very good at his chosen field of expertise.
