Sure - projectile is one of the packages that convinced me to migrate from vim to emacs. It curates a notion of "project" and maintains a list of projects you visit. My workflow is based around a lot of using projectile-find-file, which prompts you for a known project, then dumps you into an completion interface to open a specific file.

Projectile works OOTB with .git directories, so if you visit a git-controlled dir it's added to your projects. You can similarly specify other directories as projects by putting a .projectile file in them, and the contents of the .projectile file act as an ignore list.

So the workflow is work/myMonolith is the git controlled root, while I have work/myMonolith/frontend/.projectile and work/myMonolith/backend/.projectile. So I can use the project-scoped find file, grep etc. to inherently narrow the search space to that module. When I'd want to globally search, I'd use projectile-find-file (or grep, or whatever) on the myMonolith root.
