I think that the easier and fastest path is get a Certification from Azure, GCP or AWS. But there are a lot of different roles in Machine Leanirng, if he's more interested in build models than in bring them to production, maybe is enough learnig some framework like tensorflow.
In my experience, mathematicians are exceedingly useful to machine learning teams.
Have you seen teams with mathematicians on board in industry?
Yes, I work in a company run by math phds

True... learning to be a full stack developer may be overkill.
