After a few years working with free and open source companies and facing the "growing pressure" of our customers, we decided to create a company whose positioning would be focused on technical expertise. Indeed, many players have made their job integration of open source solutions, but they are, quite rarely, to offer exclusively a high level of expertise.
It is in order to fill, in part (we do not pretend to be unique), this gap that we decided to create Worteks. Worteks' objective is to bring together and put at the disposal of its clients high-level skills in this sector, which is essential for information and communication technologies.
