About us

Community

We believe in tech communities. As leading experts, we realize how important it is to share knowledge and exchange experience. That’s why we actively launch initiatives, start meet-up groups, and speak at and organize conferences. This all contributes to the creation of a networking space where state-of-the-art software technologies are promoted and ideas are exchanged.
