We also built a complete participant cabinet where drivers can:
- see their status
- track collected coupons
- monitor progress in real time
All states were illustrated—from first visit to heavy use.
We engineered the form and dashboard to handle
35,000+ concurrent drivers:
- Optimized SQL queries for the real-world load
- Live sync with Google Sheets for up-to-date stats
- Flexible screen states, from empty to coupon-packed
After entering their phone number, a driver instantly saw how many rides they’d made, how many coupons that earned, and their current odds in the draw.
