I give trainings on IT technologies (SQL, Java, XML, HTML/CSS, JavaScript, Angular, React, Linux) and methodologies (Design Patterns, Scrum), plus a little bit of soft skills (communication, emotion "management").
I grew an interest in Unix while working on Solaris 2 at the end of last century, became passionate about Linux from '95 on, and started looking for alternatives a couple of years ago, realizing Linux had become the "thing" of a few multinational corporations.
My interest in *BSD has nothing to do with my work, for which I use Void Linux. However, if it were possible, I'd prefer to switch to one of the BSD, as I feel a better "fit" with them.
