That describes a past gig of mine which was fantastically successful. I was handed a messy 3000-line Jupyter notebook which contained the prototype of a great product, and given the task of productionizing it. In fact, this is what I've done at several startups now: take prototypes and productionize them. At this point, I'm almost a specialist in transitioning from early stage to growth stage. I can do prototyping, but I recognize that productionizing is my stronger suit. The technology for the prototype doesn't matter — Jupyter is fine. In fact, it's better if the prototype is shite because then it makes it easier to make it the "one to throw away".
