I have a somewhat similar profile to you, background in computer science and design and visual arts. I have been working independently for around 15 years now and I ended up adopting a 'title' of Creative Technologist. I picked it up because... I like it or to be precise I like how it reflects what my interests are. This being said, I don't think it does much to improve my business which is based on word of mouth referrals and demos of my previous work. That's my brand as the consultant. It's not really the title, but people mentioning my name to new potential clients who ask for somebody who does creative technology... I don't think they actually use the Creative Technologist label in these conversations/referrals. And in my last full-time job before before going solo I had a title of Messenger. I was the connector between developers, designers and business teams. I thought it was appropriate, but I don't think anybody ever used it in conversation. It was a good conversation starter when handing in my business card, though!
