I'm comfortable with everything from writing CSS and React.js to building custom linux distributions and turning them into AMIs or docker containers.
I've been a professional software developer since 2005 but spent plenty of time hacking on opensource and tinkering with linux as a young whipper-snapper before I ever got paid for it. I spenty many years in datacenters racking and configuring servers. I currently run my own homelab and half-rack out of a datacenter.
My technology stack of choice is Python, Rust, React.js, and Postgres but I'm not very picky. I've worked professionally with PHP, C#, and Perl as well.
