I have worked with a huge range of technologies in addition to the ones listed in depth.

Languages

I'd consider myself language agnostic. I have done a sample coding exercise in over 20 languages ranging from Rust to Fortran.
While I have my favourites I won't let language stop me from finding a great opportunity.
Languages I've written code in include: C, C#, CommonLisp, Clojure, Dart, Elixir, Fortran, Go, Haskell, Java, Kotlin, Lua, Powershell, PHP, Python, Ruby, Rust, Bash, Swift, Typescript
