I'd love to read through some production Saturn and Giraffe setups - is any of your stuff public?
I see questions frequently about data access and serialization/validation in F# web apps, which I had specific sections about. Hopefully I'll have some time in the near future to continue the work.
In the mean time feel free to DM me any questions. There's nothing too fancy about the code. If you looked at other production code, and swapped out what your best guess for the F# translation would be, you're probably most of the way there.
