Built an interactive map for Gyeonggi Province local currency merchants (31 cities)
I built an interactive map (React + Vite + Leaflet, Firebase Hosting) that shows local currency merchant locations across Gyeonggi Province in South Korea.
What makes it useful:
- 31 cities unified (each city used to have its own page with no map)
- Business-type chip filter (restaurants, cafes, convenience, academies, salons...)
- "Open now" real-time filter — only shows merchants currently open
- PWA installable — no app store, just add to home screen
- KakaoTalk share with OG card preview
Built solo over a few weeks. Source data from official Gyeonggi Province open API.
