Stack

Flutter, Dart, Firebase Auth (Social Login), Firebase Crashlytics, FCM

Outcome

The problem

Expats and residents in Korea and Japan struggle to find local community — language barriers and urban anonymity make it hard to connect with people in your own neighbourhood.

The approach

  • Built location-based group discovery so users see communities anchored to their living area.
  • Integrated social login (Apple, Google, Kakao) for low-friction onboarding across Korean and Japanese users.
  • Implemented Firebase Crashlytics for production stability monitoring and FCM for group activity notifications.

The results

  • Live on both App Store and Google Play in Korea and Japan.
  • Location-based community matching driving organic group formation.
