Achieve Optimal Efficiency for your Developer Experience Teams

Developer Experience teams are quite popular these days as organisations understand the value of optimising for developers productivity.

At Monzo, we have a Developer Experience team that aims to meaningfully increase velocity by landing exceptional developer experiences, for example we delivered a Feature Flag and Experimentation Platform across Monzo to increase experimentation by 50%.

In this presentation, we bring you insights and learnings from our experience, with particular focus on:

  • Getting the right people and tools in place for a successful Developer Experience team
  • Building impactful Developer Experiences that matter
  • Communicating effectively about the impact of a Developer Experience team

Interview:

What is the focus of your work?

I am an Engineering Manager, focusing on enabling my teams to achieve operational excellence in order to deliver delightful experiences to the rest of the engineering organisation at Monzo.

What’s the motivation for your talk?

Developer Experience (DexEx) is still a very new practice and I believe it is not well understood across organizations. I want to share my experience building and operating DevEx teams.

Who is your talk for?

Any engineer who wants to make an impact in the DevEx space, or any engineering leader who wants to learn how to support engineers in this space.

What do you want someone to walk away with from your presentation?

I want them to be convinced that you need strong product acumen to be a great DevEx engineer.

What do you think is the next big disruption in software?

I see a lot of potential in platforms that enable integration between AI agents to leverage multiple models across user flows, and not limited to discrete tasks.

Your Platform is Not an Island: Embracing Evolution in Your Ecosystem

Monday Apr 7 / 03:55PM BST

As with most forms of engineering it is easy to talk about theory in the abstract, but typically more nuanced to implement. Platform engineering is no exception. While the term has become increasingly popular over the last few years, it is a concept that is organically evolving within industry.
