Challenges & solutions

Building reliable offline-first architecture that handles complex form data, photos, and signatures without internet was the core challenge. Implemented a persistent sync queue with conflict resolution — local changes are stored and synced to Firestore once connectivity is restored. Multi-tenant data isolation required a carefully designed access control layer to ensure dealers only see their own data.
