Overview
A zero-dependency single-page app with Google sign-in, serverless sync between phone sign-ups and a desktop admin console, Excel/CSV/JSON export and a digital membership pass.
The problem
Run registrations, member records and ID passes for a motorcycling club and its women's wing, Kundavai Krew, without spreadsheets passed around by hand.
How it works
Chennai Thrillers is a riders' club of 500+ members with a women's wing, Kundavai Krew. Before this, registrations and member records lived in spreadsheets passed between admins.
Riders sign up from their phones with Google, and their details sync through serverless functions to a desktop admin console. Admins can export the member list to Excel, CSV or JSON, and every member gets a digital membership pass.
Photos are compressed in the browser before upload, so a 10 MB phone photo becomes about 50 KB. The whole app is built without a framework.
