After taking over management of dxw’s operations team, I hired more people to the team, defined a progression framework for the team members, and line managed and mentored the five people in the team. I restructured the team by splitting out workplace IT management to a separate role, in order to prevent the work of the operations engineers from being.

In my first role at dxw, I helped to define and build our new scalable hosting platform on AWS using ECS and other AWS tools, with Terraform for configuration, as well as some custom tooling to control all our client infrastructure. I acted as product manager for this platform and also worked on client infrastructures where needed.I introduced the team to.

I empowered the community to self-organise events and to share learnings between teams, and I also.
