Problem
Coordinate hundreds of volunteers across multiple World Cup serve days without spreadsheet chaos, missed shifts, or manual email lists.
Solution
- Public marketing site with volunteer signup and shift picker
- Firebase Auth volunteer hub with role-specific content
- Cloud Functions for scheduled daily role digests
- Apps Script Gmail pipeline with bounce handling
- Multi-day media gallery on Firebase Storage
Results
Processed 500+ volunteer signups in the first month without spreadsheet chaos. Manual coordination dropped an estimated 70%. Leadership stopped manually sending digests — automated pipelines handle daily role content and roster sync to Google Sheets. The platform stayed stable through peak signup weeks with no downtime during serve days.
