Labani Delivery Engineering focus
Offline-aware delivery operations · Flutter · REST APIs · Google MapsProduct context
Delivery logging cannot assume a stable network connection, while route and driver state still need to remain usable in the field.
Responsibilities
- Implemented background location and Google Maps flows for drivers.
- Designed local logging that synchronizes with remote services after connectivity returns.
Technical challenges
- Preserving delivery activity during network loss and reconciling it when connectivity returns.
Engineering decisions
- Keep delivery logs locally until remote synchronization is available.
Reliability approach
Local persistence keeps delivery activity available during network interruptions and supports synchronization when connectivity returns.
