Server administration as freelancer
A managed server at your usual hosting provider is not flexible enough? But you don't have the know-how or the resources to take care of a server completely on your own? I will take care of setting up, securing and operating the server for you, regardless of whether it is Debian/Ubuntu or RedHat/CentOS.
Depending on your needs, I configure web servers (Apache & nginx), PHP and MySQL/MariaDB databases. When suitable, I also use Docker to run individual application components in their isolated environment.
I use ansible to automate the setup. This helps me provide an identical setup on other servers at any time. Furthermore, I avoid human error sources such as typos or forgetting.
