With all due PC apologies to female Kudoz users, the expression to use is given above.

With reference to marianne‘s answer:
- I would stick with the original structure. The wonder-person is not only capable of the problem solving stuff, he/she actually does it. There is a difference.
- Also, I’m not keen on using “affaires”, which really denotes a particular area i.e. sales/negotiation, for “business”. Far better to go with something more general such as “professionnel” or “en entreprise”.
- aren’t the problems complex?
- but I really like “en faisant preuve d’un sens aigu…“ (de l’entreprise)
