About
I am a versatile developer specializing in mobile app development with four years of experience building numerous mobile applications that have reached over 200,000 active users. Currently, I work as a Flutter/Dart developer at Orkester, a mobile and web development agency, where I am responsible for the development and maintenance of five iOS and Android apps. I focus on performance optimization, complex data handling, and architecture design to improve user experience.
My past roles include technical leadership at Apside, where I supervised junior developers and managed project deployments, and software analysis and maintenance roles at Apside Clermont-Ferrand and Michelin-CGI. I hold a Master’s degree in Software Development specialized in Mobile and IoT from Lyon Ynov Campus, and I am seeking a mid or senior developer or lead developer position preferably in a hybrid or full-remote role around Lyon, Chambéry, and Grenoble.
