Session Summary:

Internal packages are great for boosting productivity and promoting good practice, but what kinds of challenges do we face when designing solutions for multi-lingual teams? Here I will advocate for a design approach we are using at Bumble to build Python and R packages with the same foundations. I will discuss the benefits of this approach for the developer and the wider organisation.
