OASIS v1
A zero-cost café back office with Google Sheets as the database.
What it is
Operations And Sales Intelligent System. An Angular PWA over an Express API where staff logged sales, closing cash counts and expenses from a phone while I kept the raw data in a spreadsheet I could edit. It ran the shop for two months and became the blueprint for the Android POS.
