The data scientists in our team uses Flask app to run the ML models.
As part of a Migration practice in tune with client requirements, they wanted the Consulting team to re-code (& deploy) the complete Flask app into a POC Django based app (incorporating as many features as possible).
Fun part was - we had just 2-weeks to do that.
And we did not do Django before !
For the next 2 weeks, we dug-up the entire Youtube ecosystem - picking whatever we could to boot the Django buddy-boy up and running.
Client liked the POC (had few review comments though).
Overall it was a good fun experience.
