Best: The A/B test engineer for Travelocity. My velocity was only limited by the quantity of traffic to the site and there was always so much to learn from financials, human behavior, code performance, code quality, and more. Worst: A small company with a niche SAAS product that sucked. It was drowning in tech debt with no internal automation. Insecurity was high, Regression was high. Velocity was low. Everybody had an opinion and opinions always won the day resulting in an experience that continued to suck and cannibalize itself.
