I've been programming professionally close to 16 years. Here is what I can remember of my code:

# Job 1 (3 yrs)

  - Worked on around three products, all shut down, code probably lives in some SVN archive.
  - Learnt advanced JS, PHP, MySQL, Photoshop, jQuery etc (skills mostly relevant)

# Job 2 (1.6 years)

  - Project never launched, code never saw the light of the day. Probably lives in some Git archive.
  - Learnt a few in-house frameworks (irrelevant) but also leant Git (relevant)

# Job 3 (8.5 years)

  - Worked on several products, the biggest one is still active and seeing millions of users weekly. Rest got shut down and live in a Git repo.
