Experience

  • Junr
    Development of a videoconferencing application
    SOFTWARE PUBLISHING
    June 2024 - November 2024 (4 months)
    Belleville-sur-Saône, France
    I developed a desktop videoconferencing application for adults (Windows & MacOS) with FlutterFlow and Xano, then Flutter and NestJS.
    Agile methodology work (1 sprint = 1 week) with another developer.

    Key features I was involved in:
    • Two-factor authentication.
    • Onboarding and profile creation.
    • Instant messaging system (websockets).
    • Room listing (video calls) and camera layout (with pins).
    • User listing with multiple filters (location, tags, preferences…).
    • Contact favoriting.
    • Real-time connection status system.
    • Real-time call system.
    • Settings tab (account, notifications).
    • Anti-screenshots / anti-recording
    • And more…

    Stack used:
    • FlutterFlow (then migrated to classic Flutter)
    • NestJS (backend)
    • Prisma (database interactions)
    • Socket.io (real-time)

    What I would have liked to do better:
    I learned a lot during this 4-month project, but some shortcomings remain.
    • Better server security.
    • Starting with a maintainable architecture avoiding technical debt.
    • Starting directly with Flutter given the project's scope.
    These are the points I would have liked to implement but couldn't due to lack of time or skills. As I write this, I am improving these skills.
