01What it was
A hotel operating system for Indian homestays, hostels and hotel chains.
02The problem
Hotels run on money and trust at the same time. Every figure on every screen had to be provable, not just displayed.
03What we built
- Real sign-in with Supabase Auth, on a live Postgres under row-level security
- A hash-chained ledger; 46 screens and 113 business-logic modules
- A /proof page that counts what is real from the source, at every build
04The result
A hotel system that shows its own working. Trust becomes something anyone can check, not a promise.
