I want to launch a clean, user-friendly mobile application that lets customers in Saudi Arabia book limousine services directly from their phones. The app’s sole focus, for now, is booking rides. Users should be able to choose between two ride types—single trip or round trip—and confirm each reservation instantly within the app. A seamless, secure payment gateway is essential.

I’m building a Nirbhay-style flow on my Shopify store where a vehicle owner scans a QR code fixed to the car or bike, pays through a mobile wallet, receives an SMS-based OTP, enters it, and sees an instant “Activated” screen.

Key flow • Scan QR → Mobile-wallet checkout → SMS OTP → Text-based activation page → Success confirmation (show vehicle plate & tag ID). • Handle unlimited vehicles per customer; each tag keeps its own activation and usage history. • Commission ledger...

I’m embarking on an ambitious project to launch a pair of operating systems — one for mobile devices and one for desktop / laptop computers. I deliberately chose Both platforms because I need a seamless experience across phones, tablets, and traditional PCs, without depending on Android, iOS, Windows, macOS, or any other pre-existing stack. The mobile side will be entirely Custom, so we’re starting from a clean slate and can define the kernel, UI layer, and security model exactly as we want. Here’s the flow I have in mind. First, we’ll specify hardware targets and draft the architecture (kernel type, driver model, boot process). Next comes a minimal viable OS for each platform: the desktop build must boot, recognise core peripherals (storage, networking, disp...
