Hi there 👋 🦊

I'm a data engineer based in Wellington, New Zealand. I mostly write R and Python but have dabbled in a few different things over the years.

Stuff I made

I maintain some open source R packages:

  • 🍦 icecream makes print debugging a little sweeter.
  • 🛸 levitate does fuzzy string comparison.
  • 🕸️ foodwebr draws function dependency graphs.
  • λ lambdar helps you run R on AWS Lambda.

Please try them out! If you want to contribute code or feedback that would be awesome

Stuff I'm learning

Stuff I write

I sometimes blog at


  1. levitate Public

    Fuzzy string matching in R. Inspired by Python's fuzzywuzzy (but without the Python).

    R 28 2

  2. icecream Public

    Never use `print()` to debug again.

    R 13 4

  3. cypher-rs Public

    Vigenere cypher implemented in Rust


  4. rmsfact Public

    Display a randomly-chosen "fact" about Richard M. Stallman. This is a Python port of the R package of the same name.
