Interactive Australian Health GIS Mapping

I'm seeking a GIS specialist skilled in QGIS to create an interactive GeoJSON map of Australian Health Service Districts. The map will be for web-application functionalities used in a React app (likely we will use React-simple-maps).
I've included existing maps of the health service districts for each Australian state.
I want simple maps with border lines for each district and state only, nothing more is needed.

Key specifics include:
- Employing QGIS (or ArcGIS) for map generation.
- Crafting basic outlines of each health district.
- Ensuring the final maps are optimized for interactive applications using react-simple-maps.

Ideal Candidate:
- Proficiency in QGIS software.
- Experience in creating GeoJSON formatted maps.
- Familiarity with interactive mapping techniques applicable to web platforms.

If you have a portfolio showcasing similar projects, please include it in your proposal. Your bid should reflect not just your expertise, but also your understanding of the interactive aspect of this project. Looking forward to collaborating with a detail-oriented GIS expert.
