How to use FreeMonad to build data pipelines for AI

I will present how to use FreeMonad to build data pipelines for AI. Will try to focus not on what FreeMonad is, but how we may take advantage of it and build readable, efficient and robust data pipelines.
The approach I present will focus on building pipelines that are build around business rules, not around Spark data frames.
We all have pretty little things laying around in our codebases, yet, we seldom give them the same love
