I am currently working as a Senior Engineer at Atlassian.
Personally, I am trying to improve my Rust skills. I built sysit, a light weight tool to monitor system resources. Primarily, for my Raspberry Pis. Lately, I have been also contributing to helix editor. It looks promising to me. Although, Neovim's still my go-to. Hopefully, I'd get to write Rust professionally.
Python and Haskell are the languages I think code in. Professionally, I have worked with Python, Ruby, Clojure and Java.
