You may be well-suited to join an investment bank in their IT department. Honestly I have no idea what those thing you mentioned are
but usually ibanks have pretty sophisticated softwares that are probably along the lines of what you do now.
Alternatively you could become an ibanker who specializes in technology, doing IPO M&A or whatever for technology clients, but you might find your current skills would translate less into this position, and you would need to start afresh competing with MBA types.
MBA is definitely a great way to break into ibanking, if you go to a top school. A lot of people make their career switch this way. Some people also get a Masters of Financial Engineering, a new kind of degree. It's only one year and is Very math-intensive. As for other Master's programs, they are no really other feeder programs that I can think of.
I'm sure some of the people you work with now probably have some tangent connections to the ibanking world. Are you in a major banking city like NY, SF, or Chicago? Try to talk to somebody in person, I find I learn so much more from one simple conversation rather than googling for days on end by myself. Of course, tPF is a great resource too!
