Try describing what you do instead of labelling it. "I'm building an app that helps blind folks read".

Personally, I'm allergic to the word 'Entrepreneur', whenever I hear it I wince. Just say what you're building, plain and simple. I also wouldn't call myself a Web Architect, I don't really understand what that means, it just sounds fancy.

Also consider not giving yourself a title at all. If you really want a title, I'd go with something humble like "a guy who builds stuff on the internet".
