About
Hi, I am Nikolaos.
I am a System & Cloud Engineer based in Greece. I also make videos on YouTube and write books.
My day job is designing, securing and operating cloud and on-premises infrastructure. The channel and the books are where I explain what I learn and tell stories I care about.
This site collects all of it in one place. If something here is useful to you, the newsletter is the best way to follow along.
