My work calls me a Senior Software Engineer
I know Ruby, JS (vue.js, etc), Erlang/Elixir, HTML/CSS. I have built side projects in Rust, Clojure (my love), and Go.
I've been using Linux and MacOS forever and know both really well (although some linux are weird).
I'm technically a front-end dev but I've run my own web businesses where I did everything from design, marketing, PR, server, ets.
