Cross-Platform Visual Graphics App

I’m moving forward with a single code-base application that lets users design promotional visuals on both mobile and desktop. The core focus is an intuitive, Canva-style experience rather than long-form text or video editing.

Scope of work
• Build native-feeling installers for iOS, Android, Windows, and macOS (web wrapper or PWA support is a plus).
• Integrate the following must-have creation tools:
– Template library with easily updatable categories (flyers, posts, banners, etc.).
– Drag-and-drop editor that handles images, text boxes, icons, and shapes.
– Layer management so users can reorder, lock, hide, or adjust opacity with familiar right-click or long-press gestures.
• Export finished graphics to PNG, JPG, and PDF without noticeable quality loss.
• Cloud or local save options; the choice of backend is flexible as long as the code remains modular.
• Provide full source code, build instructions, and a quick-start guide so future templates can be added without touching the core logic.

Acceptance criteria
1. A tester on each platform can install the app, open a template, drag assets, rearrange layers, and export within two minutes.
2. Exported files match the on-screen design at 300 dpi with no cropping errors.
3. Build scripts run cleanly on a standard CI pipeline (GitHub Actions or similar) producing release binaries for every platform listed above.

Feel free to propose the tech stack—Flutter, React Native + Electron, or any efficient alternative—so long as it meets these requirements and remains easy to maintain. Show More
