I need a clean, reliable follow / unfollow system added to my social-media platform. When a user follows or unfollows someone, the other party must receive an in-app (and, if the framework already supports it, push) notification. Everything should feel instantaneous and remain consistent across web and mobile clients. To keep it straightforward, here’s what I expect: • Fully functional follow and unfollow endpoints wired to the existing user database • Real-time notification trigger on each action, respecting the project’s current notification framework • Basic rate-limit or debounce logic so duplicate requests are handled gracefully • A short setup guide or inline comments so my team can extend or refactor the code later I’ll provide access to the current repo and a brief architectural overview once we start. Let me know if you need specific SDK versions or API docs from my side, and please flag any edge cases you think we should cover before coding begins.
