Offline-First Task Manager — interface preview

Overview

A task-management app designed to work fully offline: every action is written to local SQLite first, then reconciled with Firestore through a custom synchronization engine once connectivity returns.

Solution

The sync engine tracks local mutations and resolves conflicts on reconnect, rather than assuming a network connection is always available — the app is fully usable with no connection at all.

Results

A fully functional offline-first app, used to explore local-first architecture patterns later applied to Carry Go's mobile apps.
