No, just an amateur with an old Nikon D3100 and a couple lenses. Though I have a few family members who are professional wedding/family photogs. Usual equipment for them is a mac of some sort with lots of storage and Adobe Creative cloud (or whatever they call it).

I don't understand why this is so difficult to comprehend - Pros don't use gallery-focused applications like Immich or Google Photos as their primary backup solution. This is not a thing that happens. If someone does use that kind of application, then they are the exception and not the rule.
