I’m building a lightweight mobile app that lets strangers meet through a familiar Tinder-style swipe card interface and jump straight into a one-to-one chat. When two users swipe right on each other’s profile cards they should be paired instantly inside an in-app messaging screen. Log-in will be handled through social media accounts, so I need seamless Facebook, Google or Apple authentication out of the box, either email, or phone number too. The core experience must feel fast and playful: smooth card animations, instant match confirmation, push notifications on new messages, and a simple profile setup that pulls name, photo and age from the user’s social account. Any additional profile fields should remain optional to keep onboarding friction-free. I’m happy with a clean React Native or Flutter codebase as long as both iOS and Android builds ship together. Real-time messaging can sit on Firebase, Supabase or a comparable cloud backend—whatever you propose as the leanest route to production within a month. Please attach a concise but detailed project proposal that covers: • the tech stack you favour and why • a milestone breakdown ending in TestFlight / Play Store betas within four weeks • how you’ll handle social login, user matching logic, and chat persistence • references to at least one past swipe or chat feature you’ve shipped Final deliverables: source code in a private repo, compiled apps ready for store submission, and a brief hand-over document so I can maintain or extend the project after launch.
