Worked on the linagora/tmail-flutter repository to implement centralized error tracking by integrating Sentry throughout the Flutter application. Leveraged Dart and YAML to configure Sentry error reporting and automate source map uploads, enabling enhanced stack trace visibility for production issues. This integration improved the debugging workflow by providing richer crash context and traceability, allowing developers to triage issues more efficiently. The approach focused on strengthening app reliability and reducing the time required to resolve mobile errors. By utilizing DevOps practices and Docker for deployment, the work contributed to higher stability and better user satisfaction through proactive error monitoring and streamlined diagnostics.
