I made my first steps in the Internet/Web around 2010 as a PHP developer. I quickly wanted to administer my own servers and run my own hosting services for clients. This motivated my to learn advanced administration skills and networking. Today, I administer a few servers for hundreds of users and I setup networking in small offices. This unusual path, moving from Web development to system administration, gives me a better understanding of both sides. I understand the development process, as well as the deployment aspect. I can act as a gateway between both worlds as a DevOps. I am curious and always ready to learn new technologies in my free time. I have got 10+ years of experience as a system administrator and technical support in a hosting company, providing shared hosting services and VPS. I regularly assist development teams to deploy their applications, especially using Docker.
