Yaniv, does your Jenkins build all your local branches? I don't have much to share, my environment is even simpler. I am sure it's a common knowledge but still a reminder (even if a new developer can benefit from it, it will be good) - you can create a database schema per each branch you work on, and if needed to switch between branches, you don't have to destroy your current database.
