I am a Site Reliability Engineer for a company that sells Kubernetes as a service to its customers.
For that reason, I know Kubernetes very well both from a user and an administrator point of view.
I worked with many cloud providers, including AWS, GCP, and Azure.
I have also backend development experience, especially in Ruby on rails and more recently Golang. I can also work with node.js if needed.
Christian did an excellent job on our project and I have been very happy with his performance throughout. He carefully read the requirements and asked follow-up questions to identity potential problem areas. His English is perfect, and communication was frequent over the project. The Ruby on Rails code he provided is very high quality, and with good test coverage. It's obvious that he cares deeply about his work, and he has a strong ethic. I would not hesitate to hire him again and can give him my strongest recommendation.
