My first distro was Red Hat in 1995. Soon after that I found that DEBs handled dependencies better than RPMs and have been running mostly Debian-based distros since.
At work we use mostly Windows, but also a mix of CentOS and Ubuntu. I avoid Apple computers as much as I am able, though everyone else in my immediate family has one.
My personal laptop is currently running Arch Linux, and I have probably tried at least a dozen different flavors of Linux and BSD over the years.
I worked in software development for close to two decades and have written code in so many languages at this point, it's difficult to recount them all.
I also have a fair amount of experience in other IT realms, such as wired and wireless networking, database administration, and cloud providers.
