The current version of the platform is being built as a software product. This means that we follow lean and agile methodologies to ship features as with a software project. We gradually release software in alpha and beta phases and gather feedback from users during these early stages. Every change is built locally and integrated from the version control system through a pull request.

Another important design principle is simplicity. We aim to optimize the work of the team, so that it becomes more fun to deliver our environment due to reduced complexity and ease of new feature development. Simplification leads to more agility to respond to our users' demands. We are significantly shifting towards more cloud native services.
