On my side, I don't manage all of them quite well. But those I have the easiest to come back to are by far those where I spent time automating things. Either setting up a dev environment with docker, having automated tests, integrating with a CI platform, having added tickets on a tracker platform, etc. I think the more the state is explicit, the easiest it is because I'm clearly not good at documenting stuff. Btw, I try to keep all of those things on my local server. I have JIRA, Stash and Bamboo installed, a docker registry, and a few bunch of other stuff all behind haproxy doing the SSL termination. I like using a tracker understanding code that way I can seamlessly link from/to PRs, commits and branches.
