Similar scope to yours but Java and Gitlab CI. The CI to dev takes about 15 minutes or so. A shared lib is first built and tested, then several applications are built and tested in parallel. After everything is built, things are deployed serially. About 3 of those 15 minutes are startup times for runners (no clue what we use, but it's super slow), another 2-3 for deployment, about 1:30 for compiling and the rest is E2E tests. The whole thing takes about 4 minutes on a ~2015 era Mac.
