Have you considered putting yourself out there. What I mean is that have some project that you can show as your own work. With your name on it. Work hard towards making that successful. Be it an app, a website, an open-source project, it has to be recognized as primarily your development work.

This could some day become a business or a side project as a hobby but for now it will give you a load of credibility when you go for interviews and will also give you the confidence that you need.

Good Luck!
