How do you add this to your resume?

Long story short : got out of the military and got into a job that had nothing to do with what i did in the military. Got an internship busted my ass got the job. Been on the job a little over 8 months now. It is with an aerospace company. Things are going good. But still want to keep an updated resume. Now since i have been here, I have worked on 4 very distinct projects requiring wildly different skill for each project. And i have basically been living my life on fast track working 100 hr weeks because obviously work comes home and every project had an extremely steep learning curve like i was condensing multiple 4 yr engineering degrees in weeks and months in order to contribute to the projects. The other side of it is… well some of the stuff is proprietary so cant exactly disclose all details of what i did. I want to make a jump… but dont know how do i add this to my resume. I have learned alot of things through “trial by fire” experiences and am at a point that most folks with advanced degrees come to me for solutions. ( i never went to college ). How do i write my resume for similar tech roles in this domain ?
