Senior Flutter Developer – Geo-Based Discovery App (Google Maps + Firebase + Radius Search)

Summary

-----------

We are building a travel discovery app focused on hidden locations (waterfalls, caves, campsites, etc.) that allows users to search within a selectable radius (10–200km), apply custom filters, and view results on a map.

The app is currently built in FlutterFlow and includes user accounts and saved locations. We now need an experienced developer to implement a scalable Google Maps + backend architecture that integrates:

- Google Places API

- User-submitted locations

- Geo-based radius filtering

- Admin moderation workflow

- Future international scalability

This is NOT a simple map integration task. We are looking for someone experienced in geo-indexing, API cost optimisation, and production-level map applications.

Core Requirements

-----------------------

- Integrate Google Maps SDK into Flutter app

- Implement radius-based search (10–200km)

- Implement category filtering system

- Integrate Google Places API (compliant with Google TOS)

- Store Place IDs and attach custom metadata

- Build scalable backend architecture (Firebase preferred)

- Implement geo-indexed queries (e.g., GeoFlutterFire or similar)

- Build admin web dashboard for:

- Approving user submissions

- Editing locations

- Managing categories

- Optimise structure for future API cost control

Required Experience

-------------------------

- Proven experience building geo-based apps

- Experience with Google Maps SDK & Places API

- Strong understanding of geo queries and radius search

- Firebase / Firestore experience (including Cloud Functions)

- Experience building admin dashboards

- Understanding of Google API billing and usage limits

- Flutter (not just FlutterFlow)

Bonus:

- Experience scaling location-based apps

- Experience with PostGIS or advanced geo indexing

We are open to migrating from FlutterFlow to pure Flutter if architecturally justified.
