Welcome to GMAT Club!
The MBA is about practical applications on the most part. There is no such thing as MBA with focus on XXX. You choose the focus you want while in program. You can take highly technical classes or you can take finance or marketing courses. You have set of electives to take - you decide what they are. So your background won't matter a whole lot since you won't be learning a whole lot of programming besides VBA/Excel programming and modeling.
The best you can do is get as much experience as you can and show as much maturity and leadership as you can - basically, do your job and excel in everything... that helps a lot with admission, career, and job afterwards.
