Hello, Hubert! 👋
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.
