About us

The Company

Happy Team was founded in 2015 when 5 software developers, who enjoyed working together, decided to go independent and fully unlock their potential as a team.

.NET Framework, C# and JavaScript are the tools being extensively used by the team on a daily basis. But over the course of years team members gathered experience in delivering ASP.NET MVC websites, WPF desktop applications, Single Page Applications, native iOS apps and hybrid mobile apps.

It's not only writing code but also exchanging opinions and ideas that's important for the team's growth. HappyTeam loves people and communities. Founders of DevDay and organizers of GET.NET and dev@LDZ meetup are a part of the team. Most of the team members are also successful international conference speakers.
