Summary

My focus is on supporting DevOps transformation processes, both on the technical and cultural level through analysis, evaluation, conceptual design, planning, workshops and hands-on, this individually and pragmatically tailored to the specific challenges.

"Mr. Radicke showed a high level of initiative and very good analytical skills. He supported the internal on-premise to cloud transformation process with his broad expertise. He coordinated closely with all required departments and documented his progress in an exemplary way. The results achieved by Mr. Radicke always met our expectations, and we look forward to working together again in the future."

"Mr. Radicke provided excellent support in a project to renew our CI infrastructure. For this project, we needed conceptual ideas, designs, planning support, and hands-on work in modern automation and cloud technologies like Docker, Kubernetes, and Ansible. Mr. Radicke brought all of this, enabling our team to tackle our tasks with new and more efficient tools."
