Our technologies

We use a multitude of technologies, employed over many years to build the platforms that drive our group today.

Code is kept up to date and technical debt prioritised and removed. We use Jira for ticket management, GitLab for source control and have a dedicated platform engineering team which supports a developer platform as our infrastructure estate.

We never settle, and we’re always looking for ways in which we can improve our technology estate. You can read about this in more detail here.
