Word From Our CTO

We stand out for our ability to quickly adjust to new challenges and opportunities.

“

Each project helps us learn and evolve, keeping us at the cutting edge of technology. In 2020, we shifted from PHP to Java & Kotlin and embraced Kubernetes and the cloud. We have grown our frontend team from scratch into one of the largest in the company and now use a modern stack and offer extended services.

Tomáš Ivan

Product Team

We make the extraordinary. Systematically.

“

We don’t follow trends, we set them. Our product process consists of 3 basic steps:

1. Product Discovery, 2. Product Roadmap, 3. Product Development

Michal Počuch

Project Team

Delivering all projects successfully, which includes meeting deadlines, staying within budget, and maintaining high quality standards, is our top priority.

“

The cornerstone of our work is communication, so the tools we use most are the ones that make it easier to interact with other people.

For project management, we use the Atlassian suite (JIRA, Tempo, Confluence) plus other support tools such as Product Board, Miro, Notion, and so on, depending on the needs and preferences of each PM.
