Worked on the amorphie/flutter.core repository to enhance stability and observability in a mobile development context using Dart and Flutter. Addressed cache consistency by refining the cache write logic, ensuring device information remained accurate during version changes. Streamlined analytics infrastructure by decommissioning the Posthog stack, removing related dependencies and feature flags to reduce maintenance overhead. Improved diagnostic capabilities by reworking the NeoTransitionListener logging, enabling more effective routing of failed long-polling event logs between Elastic and PostHog. Applied skills in state management, event handling, and code refactoring to deliver targeted improvements that support accurate data, leaner analytics, and better troubleshooting.
