Our mission
-
-
We know how important it is to share knowledge, which is why we not only often participate in conferences, but also sponsor meetups and conferences, such as PHPers Summit or PHPers meetups in Tri-City and Toruń. Our team actively participates in various types of local tech meetups where they are able to develop their soft and hard (technical) skills. We try to help on StackOverflow, forums and Facebook groups, and give back to the community as much as we can!
-
Our team has to find time for self-improvement in order to develop, being aware of this we give the team a free hand half a day on Fridays to run their original projects which we can then use
-
It is particularly important to us that our work environment is friendly. We know that people are diverse and it is important for us that despite these differences (which are essential in creative work) everyone feels comfortable at work. We also want our clients to feel comfortable with us!
Team
We are diverse and each of us is different, but we share common goals so we can create new quality
