How about DevOps? It fits into your "help others" mindset in the sense that DevOps is all about enabling a software team to do more efficient work. Much of the job is working right with the devs and removing all their pain points. Treat them as your customer and they will love you for it. Also, since you are a powerlifter, you obviously are a stats/metrics geek and that fits right in also.
