Your Model Isn't Done Until Someone Else Can Call It
As always, I decided to learn by building, because I still believe this is the best way to learn. The first project I chose to tackle was a churn predictor api.It's a small FastAPI app I built to predict whether a customer is about to churn. How it works is that, you feed it a customer's data, it hands back a probability, a prediction, and a risk level.
