I’m looking to have a complete barber-shop solution built that covers three fronts: 1. Customer–facing iOS and Android apps 2. A web-based admin and staff dashboard I’m open to the tech stack you recommend (Flutter) as long as the final apps pass App Store and Google Play review and the backend can scale. Please structure the code clearly, comment key logic, and provide deployment instructions so I can run the system on my own server when delivery is complete. If you have previous examples of appointment or service-based apps, link them so I can gauge fit. I value clear communication, regular progress updates, and clean UI that feels modern and intuitive.
