Postgresql jobs

I’m developing a cross-platform Flutter application that centers on location services. The core feature set is an interactive map that offers real-time tracking and turn-by-turn navigation, plus geofencing that fires events whenever a user enters or leaves predefined zones. The back end will live on Supabase with its PostgreSQL database, so you’ll connect the Flutter front end to Supabase for authentication, live position storage, and event logging. Google Maps or Mapbox—whichever you work fastest with—can power the mapping layer, provided it supports smooth location updates and low-latency WebSocket or stream channels. Flow I need: • User signs in, grants location permission, and sees their live position on the map. • Movement is tracked cont...

I already have an HR data model (an artefact generated in Claude) and I now need it turned into a working PostgreSQL database that can be accessed through a web-based service.
