I make bike parts for my job. Most are for modern bikes but some are for older bikes. Here is a step I made recently for a high-wheel bike. This was a gift to another collector who was helpful on one of my projects.

I may use the word "professional" to describe making a living with my crafts, frame building and metal fabrication but I wouldn't call myself a "bike industry professional" but more due to my objectives and behavior.
I would describe most of you with the whatever accolade you thought suited you best. As long as you aspire to gain mastery and are absolutely serious about your level of workmanship and how you describe your skills to the people you trade with, you are a pro in my book.
