Project description:
"I need a full-stack JavaScript developer (React/[login to view URL], Node.js, Supabase, PixiJS/[login to view URL]) to build a QR-based digital wishing wall.
The foundation here is Three.js.
I'm looking for a developer because the dashboard page needs to be implemented in Three.js.
Visitors will scan a QR code at the ticket booth and submit a simple wish (English/Chinese, with a choice of name and lantern color). Staff will then verify the wish through a secure dashboard.
Approved wishes should be displayed in real time on a large LED screen. They should start at the bottom of the screen and float among the existing lanterns, displaying highly realistic movement (smooth rise, sway, wind-driven movement, flickering flames, and non-overlapping crowd dynamics).
The system should include profanity filtering, speed limits, festive themes (October 10, Mid-Autumn Festival, Chinese New Year, Ramadan), and a simple analytics dashboard (number of wishes, peak hours, and popular emojis). The project includes a mobile QR submission form, a review/management dashboard, an LED wall app, and setup documentation. The wall will maintain 60 frames per second at 1080p with less than one second of latency from approval to display." (client-provided description)
