Approach

Outcome

Qualitative

Delivery apps are a background-services problem wearing a maps UI. Continuous GPS, Socket.io for live position, and route optimisation for pickup and destination — all of it has to survive the OS trying to kill your process.

What I did

Built continuous GPS tracking over Socket.io with Google Maps route optimisation, job receiving, push notifications, and custom background services in native Kotlin.
