Project description:
"I need a single code-base solution that ships smoothly on iOS, Android, and the Web. The core of the product is a clean, reliable calendar integration that helps users schedule, view, and manage events in real time. Think of it as a lightweight productivity hub: no e-commerce, no social feed—just a focused tool that keeps appointments synchronized across every device.

Here’s how I picture the roll-out:

• A responsive web app that works in all modern browsers.
• Native or near-native mobile builds for iOS and Android, delivered through the usual app-store channels.
• Seamless calendar sync (Google, Outlook, iCal) with create, update, delete, and reminder functions.
• Secure sign-up and log-in (email, Apple, Google).
• Cloud-hosted backend with real-time data updates, minimal latency, and GDPR-ready data handling.

Acceptance criteria:
— Users can sign in on any platform and see the same events instantly.
— Creating or editing an event on one device updates everywhere within seconds.
— Push notifications and in-browser alerts fire at the correct times, even if the app is closed.
— The interface follows native design guidelines on each platform and passes App Store/Play Store review.

I’m open on the stack—Flutter, React Native, or a well-maintained hybrid framework—so long as the calendar features remain snappy and the codebase stays maintainable.

Let me know how you would architect the solution, the APIs you’d tap for calendar sync, and a realistic timeline for an MVP followed by polished store releases." (client-provided description)
