Build Cross-Platform Productivity App

JavaScript, Agile Development, Node.js, PhoneGap, AngularJS, iOS Development, RESTful API · I’m starting from a clean slate and need a complete productivity app for both iOS and Android. The core experience centres on task management paired with tight calendar integration, so users can create, edit, prioritise and schedule tasks while viewing everything alongside their calendar in real time. A smooth, responsive interface and an intuitive flow are critical—swipes, drag-and-drop, dark mode and offline support should all feel native on each platform.

For the backend I want Node.js. You’ll design the architecture, build secure RESTful APIs, handle authentication, and connect everything to the mobile front-end. Push notifications—both scheduled and event-driven—must work flawlessly. Expect integration points for third-party calendar services (Google, Apple, Microsoft 365), plus room for future expansion to notes or file attachments.

Please show me live links or store listings that demonstrate you have already shipped comparable cross-platform apps with a Node.js server behind them. A brief outline of your proposed tech stack for the mobile layer (React Native, Flutter, native, etc.), estimated timeline, and milestone plan will help me evaluate fit.
