A note on this list
Three of these were never used by anyone and two were closed on purpose. They stay because a portfolio that only shows the wins is an advert. The useful question is what each one was for and what it changed.
Building them has also grown my respect for developers, because the parts I cannot check myself, architecture and security and what the code will cost to change, are exactly where their judgement lives.
