DevOps Internship

6 months + 6 months advisory role

• I designed and implemented a containerised CI/CD pipeline for the DVZ-MV. This included all technical and non-technical processes and the infrastructure. This was done by building on the existing infrastructure (BitBucket, Jenkins) and deploying an OpenShift cluster to enable Continuous Delivery and improve Continuous Integration. The lead time of the CI pipeline was reduced by 60%.
• This implementation served as a reference for a subsequent project that ran for 2 years and enabled container-based workflows within DVZ. I supported this project through a series of trainings, lectures and reference implementations.
