WINE AND SPIRITS

Took over the development of the Solera project, a B2B application for managing the aging process of wine in cellars. The objective was to update the technology from Xamarin to Android Java. Subsequently, converted the Java code to Kotlin. Finally, developed the Solera SCAN application.

As technical support, integrated into a team of 6 people (including 3 developers), using the SCRUM agile methodology, I participated in:
- Setting up CI/CD in Azure DevOps with the help of DevOps engineers
- Setting up Sentry (automatic error reporting)
- Improving SCRUM processes, coding best practices, and application deployment
- Architectural redesign of the existing application, research and implementation of third-party libraries
- Implementing the technical aspects of the application: scanner, data synchronization, asynchronous call management, creation of specific graphical components, unit tests
- Developing the Solera application and managing the two developers in the team
- Developing the shared content provider library, an API allowing other applications to consult Solera's database
- Developing Solera SCAN, an application providing details on a scanned barrel, with a Jetpack Compose interface
- Developing the Inventory (phase 2 of the Solera application), using Kotlin Coroutines
- Refactoring Solera to full Kotlin.
