↖ move to x-ray · or flip to Codeflip to Code ↗I’m Hasan — rentonhead, a software developer. I build the software businesses run on every day, and I host it too.
Some of it is ready to deploy for you today — point of sale, QR menus, online ordering, delivery operations and school payments, all proven in real businesses. The rest I build to order: platforms, integrations and iOS & React Native apps, from the data model to the server they run on.
