Welcome! You might be interested in our two newest case studies, from
@fresh-cat-90827 about Oxbotica's use of Pants and from
@high-yak-85899 about Astranis'. Alexey in particular addresses their use case in developing autonomous vehicles, and Nate goes into detail about why they chose Pants over Bazel. Both are very DS-/ML-heavy use cases.
