Our goal is to build a strong community of developers. We always try to introduce appealing presenters, both Czech and from abroad, that, we believe, can fill our attendees with enthusiasm and widen their knowledge.

Update Days

We like to do things that make sense. That is why we hold high-quality medium-sized conferences under the Update Days brand, which focus on current interests of Czech developers. If the topic of the conference demands it, we also try to get foreign speakers to the event.

Update Talks

At our events and elsewhere, we like to talk to presenters from abroad and from our home to later publish the interviews as part of Update Talks.
