Its just that you moved from an environment where you knew the product back to front and how everything fit together really well to a new environment that you understood less.
I work on two microservice cloud systems at the moment: the first I was the first person working on it day one, and have been involved in every aspect including devops & support for the past seven years - I'm far and away the most producive developer on this system.
With the second system, there's another developer that's driven the team for the past few years and designed everything from the start, and they are easily the most productive person on this team. Probably 3x everyone else and its a strong team.
Its just that I know the second system less - I know roughly how everything works, but haven't poked around in every corner of the system like I have the first. For larger systems this kind of knowledge can take years to build up.
