You've changed. Good. I'd say that getting your degree is one way you've demonstrated that. Once you get as far as an interview, I think that an recruiter or employer - knowing your truth about having been inside for so many years - might want to hear about other proof that you've changed. What else, besides your degree and that you are currently managing to hold down a job (well done for both!) shows that you've changed, and left the life of a convict behind you?
For example:
Do you practice a religion or spirituality, do you support your family financially or by helping them, do you life in a non-gang and non-criminal type of place, do you donate money to charity or do you do any volunteer work to make the world a better place, do you tend to a vegetable garden, do your cousins let you spend time with their children and if so do you help them with their homework, do you spend time developing your abilities in any kind of hobby, do you cook your own food, do you play a team sport, have you read any self-help books or do you follow a life-coach or philosopher online?
Are there any people you know through any of the above who would give you a character reference or something like a work reference, e.g. for your volunteer work?
