I design and write software, been at the same employer for over 13 years, and am by far the most senior and experienced coder on the development team. I've been doing this professionally full-time for almost 20 years, but did free-lance stuff off and on for more than 10 years prior while doing other technology work to pay the bills.
My first paid gig was for a long-since defunct computer hobbyist magazine when I was 15. They had no idea I was only in 9th grade.
I generally enjoy it, though the type of work I do has become fairly routine. It pays well enough to keep me from looking elsewhere.
