Open-Source Software

R and Python packages for data analysis, visualisation, statistical reporting, and developer tooling, with 64.1M+ total downloads. The goal is practical software: clearer results, reproducible workflows, and code that is easier to maintain.

Many of these packages grew out of methodological needs in my own research. The broader context is summarised in Research, while peer-reviewed software papers are listed under Publications.
