About me

I am an IT specialist who runs corporate IT infrastructure end to end and also builds custom software where it is needed. I work on both sides: keeping the systems up, and writing the tool when one is missing.

My work spans Windows Server and virtualization, network security, Laravel admin panels and Android apps. I like making processes traceable and repeatable, which is why automation sits at the center of what I do.
