Stefan Mesquita

Chief Product Owner for API Platform at Deutsche Bank


”We wanted to treat the internal portal like an external marketplace and offer the users a five -star user experience.”


In the demo, you can hear about:

  • The goal: moving from a more monolithic-driven landscape to a microservice-driven landscape.
  • The problems faced by Deutsche Bank API Platform when adapting to the new architecture (e.g., slow adoption of APIs).
  • The solution: Compliant and UI-based API deployment process.
  •  Not just APIs, but a UI for users to publish APIs for discovery.
  •  Challenges: design an intuitive interface, raise awareness of the new product, get the buy-in from the stakeholders for a new SDLC process.
  • Fully self-service, simple processes.
  • Stakeholders using APIs offered by Deutsche Bank API Platform.
  • The result: an integrated internal API portal.
  • How the number of APIs changed since going live.


  • Digital transformation happens step-by-step.
  • Accept and learn from failure.
  • Focus on API quality from the beginning.
  • Understand and consider your user groups.
  • Deliver quality.
