I was part-time for this client (1 day per week). Initially, I created mockups in Figma to modernize the audiometry software.Then I carried out various exploration tasks:
- Development of a Flutter application with sound modulation to assess the possibility of performing audiometry on a tablet
- Investigation for the integration of a pupillometry device, either in the Windows application or on the Flutter mobile application.
I then provided assistance on the web dashboard:- Code audit and advice on best practices
- Implementation of integration tests on the server side
- Setup of automated deployment on Plesk, using Docker
- Development of certain features
Finally, I developed a cross-platform Flutter application to allow patients to fill out questionnaires. The application is launched securely and the questionnaire results are recorded in the Noah ES system (database for audiologists).Achievements- UI/UX design of the audiometry software, creation of mockups in Figma
