Thank you for doing this. Two or three sentences is plenty, on whichever of these is easiest to answer: what needed sorting out when you first got in touch, what surprised you, whether a moment stuck with you, a deadline, a call, the day it went live, or simply what you would say if someone asked whether they should hire me.
Do not polish it. Typos are mine to fix, and it does not need to be flattering, just true.
