if you need installation and administration of debian linux or windows, you can contact me. I can also make for you websites with wordpress or PHP, landing pages (HTML, CSS), etc. I can also team with other programmers and make more complex websites for you, I am from Serbia, west European companies outsource job to our programmers in Serbia, even if you pay the UK or Swedish company to make website for you, they will take programmers from Serbia to do it, they take profit and they outsource job to Serbia. You think it is made by the UK company but it is made by Serbian programmers.
In Dec. 2018, I finished and got certificates from Coursera about Windows System Administration + Introduction to software production management, now I watch second part of software production, still I didn't finish it, but it is connected with Agile software production, how to manage a team, etc.
