Cross-Platform SaaS App Development
Budget: $750 – $1,500 USD
I need a web-based SaaS that has a single code-base that can be packaged for iOS, Android, and Windows desktops while preserving a professional, corporate look and feel.
Core features to build in: push notifications on every platform, seamless real-time data synchronisation with our current back end, secure member log-in protected by two-factor authentication, one-to-one peer messaging, and the ability for users to create and manage groups inside the app.
Design assets and brand guidelines are ready; you will translate them into clean, responsive UI components that feel at home on each operating system yet stay visually consistent across the suite.
Deliverables
• Source code with clear setup instructions
• Tested builds submitted to Apple App Store, Google Play, and Microsoft Store (or signed Windows installer)
• Documentation outlining build steps, environment variables, and how to extend the feature set
• A brief knowledge-transfer call or video walkthrough after hand-off
Success criteria: all listed features functioning identically on the three target platforms, no security regressions compared with the web app, push alerts reliably delivered, and apps accepted by the respective stores.
If you have a proven cross-platform toolchain in mind—React Native, Flutter, Xamarin, or similar—let me know and include relevant store links to past releases.
