I'm a full-stack (back-end-leaning) software engineer with additional background in system administration and I would describe myself as a tech generalist.
I primarily run (Debian-based) linux on my personal and side-project machines, but additionally develop on/for (and administer) Windows machines at work.
The common threads throughout my professional experience are C++ (MSVC 6–2017; Sun C, gcc/clang), parallel processing and multi-threading, and SQL relational databases.
I picked up enough C# and (unrelatedly) Android SDK+NDK between 2015 and 2018 to ship a few projects for which I was solely responsible, but I'm far from an expert. I've also worked more than a handful of days in C, Java (JRE and Tomcat), Python, bash/sed/awk/grep, PowerShell and cmd/bat, PHP, and HTML/JS/CSS.
I also became the sole DevOps engineer/evangelist at my job in 2014 out of necessity, automating various engineering and build activities, standing up and managing our git server, ticketing system, wiki, and am [aspirationally, at least] working on CI.
I took the full curriculum (but not certification) for CCNA, and took classes for and received my certification in project management (PMP).
