PrivateBuilt for the mountains: a full supermarket ERP that keeps selling when the power and internet go
A supermarket in the mountains of Duhok, where electricity and internet drop every day. Instead of a smaller system for a hard place, the store got everything a big store has: 4 cashier lanes, stock, accounting, label scales, fingerprint attendance and an owner app on the phone. Every part has a fallback. If the internet drops, the lanes keep selling. If the store's server stops, they switch to the cloud. When everything comes back, every sale lands exactly once. Built by one engineer, checked by 736 test files, and published as a research paper.
