Experience.

Flutter App Development Intern

@ The Xpertz

June 2024 – Aug 2024

Implemented real-time client-side data synchronization in Flutter using Firebase Firestore listeners and REST endpoints, enabling dynamic record updates across client sessions. Stabilized a production mobile application by resolving 15+ UI and state defects, modularizing shared UI widgets, and implementing automated unit tests for API parsing models.
