Jeppe worked on targeted stability and efficiency improvements across kubernetes-client/python and localstack/moto. In kubernetes-client/python, he addressed SSL verification failures by restricting urllib3 to versions below 2.4.0, ensuring compatibility with Python 3.13+ and older AWS EKS clusters. For localstack/moto, Jeppe optimized Docker image builds by enabling editable installations, introducing a dockerignore, upgrading the Python base to 3.13, and migrating to an Alpine-based image. These changes, implemented using Python and Docker, reduced image size and improved deployment speed. His work demonstrated depth in CI/CD, dependency management, and DevOps, resulting in more reliable deployments and streamlined iteration.
