I specialize in developing React Native + Node.js/Python solutions with geolocation, OpenStreetMap, PostGIS, and H3. I am ready to create an MVP for you of an interactive widget and mobile application considering all requirements:
⭐ A widget with a rating system, time limits, and data synchronization.
🗺️ A mobile application with a hexagonal map (OpenStreetMap + H3 Uber Index), filters, and anonymous statistics.
⚙️ A backend on Node.js or Python (FastAPI / Express) with PostGIS for working with GPS and H3.
…
🔐 Scalable architecture, ready for expansion after the MVP.
I have practical experience in creating similar systems (maps, ratings, spatial databases). I work with attention to UX, performance, and code quality.

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.

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 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!
