BRANDING HEADLINE

Co-author of bash Cookbook (O’Reilly 1st 2007, 2nd 2017) and bash Idioms (O’Reilly 2022).

IT professional since 1991, specializing in Information Security since 1997, remote working since 2002. I’m a maker, not a manager, a problem solver and force multiplier: I fixed a problem or wrote a new tool, documented it, automated it, put it in Git, built a process around it, and now nobody has to think about it anymore.
