so he was orphaned at a young age and bounced in and out of foster homes until he was old enough to join the military. he got injured, but instead of getting dishonorably discharged asked to be transferred into IT operations where he got a fuck load of computer certifications. when he finally gets done with the service he comes back to the money that his parents left for him, plus all those years of unspent military salary and finds out he can't get a job with the certs without a degree, so he starts a repair business in the interim with his money and goes to school for a bachelor's in computer science/it thanks to uncle sam. that's as far as i've explored so far but i'm open to a lot.
