Developer Experience on Kubernetes (Cloud Native Aalborg 2025)

As a developer, working with Kubernetes too often leads to too much cognitive load, inefficient inner development loops, and friction in the path to production.
This session is structured as a series of iterations on the developer experience to improve those three aspects and boost productivity, while following an approach based on open-source technologies.
