Solo dev built a QR ordering system after watching restaurants waste time on manual orders
A solo developer noticed how much time restaurant staff waste walking table-to-table to take orders by hand, so they built a QR code ordering system where customers order directly from their phones. It's a straightforward example of spotting a real-world problem and turning it into a product.
Taking orders manually sounds simple, but it ties up staff, causes mistakes, and slows down service — especially in busy or understaffed restaurants. This developer watched that frustration firsthand and built a solution: stick a QR code on each table, and customers can browse the menu and place their order from their own phone without waiting for a waiter.
For a small restaurant owner, this can mean fewer errors, less staff time spent on order-taking, and faster table turnover. For a solo builder, it's a textbook move — find a pain point you can see with your own eyes, then build a focused SaaS (subscription software) product to solve it for a specific market.

- Reduces order mistakes and frees up staff from walking table-to-table
