Forrestia FieldOperations Platform

The solution needed to function reliably in remote forestry environments with intermittent connectivity while remaining easy to use for non-technical field supervisors. It also required robust synchronization logic to reconcile offline changes, maintain data consistency across multiple operational modules, and integrate seamlessly with an existing enterprise PostgreSQL infrastructure.

Built Forrestia, an offline-first Flutter mobile application that enables supervisors to capture operational data across multiple field modules. Records are stored locally using SQLite and automatically synchronized with a centralized GraphQL/PostgreSQL backend whenever a stable internet connection becomes available.

The Flutter application uses GetX controllers and an MVC architecture to manage business logic across four operational modules. User actions are immediately stored in SQLite with synchronization states, while SharedPreferences maintains sessions and cached data. Once a validated internet connection is detected, a GraphQL synchronization service uploads pending records to a PostgreSQL database, reconciling newly created, updated, and deleted records sequentially.
