Adam Stańczak

Head of Application Department at ENERGA Informatyka i Technologie Sp. z o.o

The proposed by Sii Poland candidate turned out to be a perfect match for our projects. As a Project Manager, he impressed us with his professionalism and ability to learn quickly. If all Sii’s outsourcing resources perform so well, I highly recommend the company.


Gabriel Buchała

Chief Engineer CBU DELPHI

Sii Poland’s engineers are specialists who live up to our expectations as to their knowledge, ability to carry out most complex projects, work style and adopted approaches. As other corporations, we are obliged to follow certain procedures, processes, thus, even the project launch and commencement of cooperation with Sii required from Sii maximum flexibility, which in fact, came to us a pleasant surprise!
