Multi-Platform ATS Resume Builder

I want to launch an ATS-friendly résumé creator that offers the same smooth, guided experience you see on https://enhancv.com/, but packaged for the web, mobile phones, and desktop computers in a single, maintainable code-base.

The look and feel must stay firmly professional—clean lines, generous whitespace, restrained colour palette—so a finished résumé looks hiring-manager ready straight out of the tool. Users will browse a gallery of editable templates, type or paste their details, watch real-time changes, and finish with a document that sails through Applicant Tracking Systems.

Three functions are non-negotiable:
• A library of fully Customizable Templates, each section drag-and-drop or on/off toggle.
• An ATS Compatibility Check that scans content/layout for keyword density, section order, and parsing pitfalls, then highlights fixes.
• One-click export to both Word (DOCX) and PDF with identical formatting across all platforms.

Stack is your call—React + React Native, Flutter, Electron, or another cross-platform approach—so long as it delivers:
1) a responsive web app,

Deliverables
1. Deployed MVP on a public staging URL plus signed mobile/desktop builds.
2. Full source code in a Git repo with clear setup docs.
3. Short user guide and API/architecture notes.

When you reply, outline your preferred tech stack, any similar WYSIWYG/editor work you can show, and a milestone timeline so we can get started right away.
