Experience

  • Bubble.io
    Bubble.io plugin development - Contribution to the ecosystem
    SOFTWARE PUBLISHING
    July 2025 - Today (11 months)
    Nantes, France
    As an experienced Bubble.io developer, I have actively contributed to the ecosystem by creating 5 specialized plugins that solve common technical problems and improve the user experience:


    🔒 Sensitive data protection
    • Mask Email and Phone: Privacy solution to automatically mask emails and phone numbers before storage, particularly suitable for marketplaces and dating sites to maintain exchanges within the application's ecosystem.

    📱 Mobile and desktop optimization
    • Direct and Native Image Downloader: First plugin allowing native and optimal image downloading depending on the platform (Downloads folder on desktop, Android photo gallery, iOS share sheet).

    🌐 Browser data detection
    • Language Detector: Automatic detection of the browser's language to personalize the user experience from the first visit.
    • System Theme Detector: Intelligent and economical synchronization with the system theme (light/dark), with real-time monitoring of changes without page reloading.
    • URL Detector: Complete sharing of URLs with all their parameters, essential for marketplaces and classifieds sites using dynamic parameters.

    These plugins demonstrate my ability to identify the limitations of Bubble.io and develop technical solutions that concretely improve the developer and end-user experience.
