13 in 1981 (The first day of grade eight had me in the computer lab). I remember writing a top down scrolling vertical scrolling racing/avoid the obstacles game. load "*", 8 will forever be etched in my mind (We had PETs in school). I've been a paid developer since about '90. These days I mostly do Rails apps (with a bit of Go).

I got my first computer when I turned 14 and within a year I was writing toy programs in VB for AOL that got thousands of downloads a day. My toy programs worked really well, but I didn't start writing software at a real job until years later.

14. I used Turbo C++ and wrote little command line apps that solved polynomial equations and drew ASCII shapes :)
