    September 2019 - Today (6 years and 8 months)
    Boulogne-Billancourt, France
    Primarily worked on the MyTF1 Android application: +10 million installations, ~2 million MAU (monthly active users) in an agile environment. My daily tasks consisted of implementing new features, maintenance and bug fixing, scoping user stories, mentoring and advocating for clean code and conducting refactoring, monitoring app performance.
    Key achievements:
    - Implementation of the new home page with complex animations and transitions
    - Performance improvement (memory footprint, battery consumption)
    - Improvement of the app's stability and overall quality (-50% crash rate), which led to an increase in the Play Store rating from 3.5 to 4.3 stars.
