When we designed the home screen of the Zalando App , we faced three challenges. Firstly, the home screen consisted of several components developed and delivered by individual teams, without former native development experience. Secondly, we believe that the first impression for customers - our home screen - must have a premium look and feel, and therefore decided to build it in a truly native fashion.

Here at Zalando Tech, we’re driving the “API First approach” as our teams are making a lot of use of external APIs. Since we also depend on different external technologies for content delivery, DNS hosting, and asset storage, we want to integrate our services with them. One good example is Akamai. We’re using a variety of their offerings in order to give customers the best delivery and user experience.

There’s a lot of noise surrounding the ability of AI agents to connect to your tools, systems and data. But building an AI application into a reliable, secure workflow agent isn’t as simple as plugging in an API. As an engineering leader, it can be challenging to make sense of this evolving landscape, but agent tooling provides such high value that it’s critical we figure out how to move forward.
