# DropETA

DropETA is a prototype for arranging a changing list of deliveries, using route durations to work through stop order and the arrival times that follow from it.

[Open the application](https://dropeta.vercel.app)

Independent prototype development. TypeScript, routing services and browser UI.

I worked on the point where a new delivery changes an existing route, as adding an address is easy but the useful part is seeing what it does to the stops that were already planned, with the duration matrix giving the ordering logic travel estimates to compare as the list of destinations changed.

The implementation has duration-matrix and route services, with stop-order evaluation, recalculated arrivals and an insertion preview that tests where another stop can fit in the current plan.

The interface ties those operations to a map and a stop list, though live position access and the configured routing services are still conditions for the corresponding ETA behaviour.

The catalogue date follows the first preserved commit on 20 March 2026.

## Outcome

An implemented route-planning prototype with browser UI and stop-insertion logic. The captured interface shows the initial state, without implying a completed commercial rollout.
