I am looking for a freelancer for an MVP widget and mobile application with geolocation (React Native + Backend)

Budget: 40000 PLN Deadline: 60 days

Hello, Hubert

The Mobiwolf team specializes in developing MVP solutions with geolocation analytics, mapping integrations (OpenStreetMap, Mapbox, Leaflet), and building backends with PostGIS / H3 indexes. We have already created similar systems for urban and logistics projects, where accurate aggregation of GPS data and working with time filters are important.

We offer a full development cycle:
• Interactive widget (ratings, synchronization, time constraints);
• Web application with OpenStreetMap map + H3 visualization, filters, and statistics;
• Backend on Node.js or FastAPI (Python) with PostGIS for spatial analytics.

The MVP can be completed in approximately 8–10 weeks, the cost is $35/hour, and we will provide a final estimate after clarifying the aggregation logic, blocking periods, and user types.

We are ready to discuss the details of the architecture, H3 integration, and API format privately to agree on the technical specifications and stages.

Hello!
I have extensive experience in creating various mobile applications – both native and cross-platform – including those with GPS support and backend (Node.js / Python / PostGIS). The project looks interesting, I would gladly discuss the details and we will determine the scope of the MVP.

Hello!
I propose to implement this project in Flutter, as I already have developments on similar functionality — interactive widgets with ratings, working with GPS, data synchronization, and integration with the backend. Flutter will allow for the quick creation of both the widget itself and the mobile application for viewing the map and statistics, with a single codebase and good performance on Android and iOS.

I have extensive experience developing interactive widgets and full-stack mobile applications using React Native and NestJS.
I can deliver this MVP end-to-end: an interactive rating widget with synchronization and time locks, plus a companion app displaying OpenStreetMap data with Uber H3 hexagons, filters, and anonymized statistics.
The backend will be built with NestJS and PostGIS for precise GPS and H3 aggregation.
I focus on clean architecture, real-time synchronization, and scalable design — ready for production growth.

Hello!

I can build your MVP with a smooth rating widget, a simple mobile application, and a stable backend based on PostGIS and H3. The widget will allow users to rate, filter by time, and synchronize in the background. The application will display a live view of OpenStreetMap with hexagonal zones, time filters, and anonymous data, allowing you to observe trends without revealing user data.

To increase transparency, I will add a small playback slider in the map view that will allow you to move through time and observe rating changes from hour to hour. This will help you quickly notice changes and adjust the logic before scaling.

I have developed clear and data-focused applications, such as https://storyai.cc and https://live.chatbullet.com, where performance and usability were paramount. I will provide clear code, brief documentation, and guide you through the deployment process to ensure everything runs smoothly.

Thank you!
