Context

Wolt+ offered free delivery within a defined radius, but users outside that range saw limited benefit — reducing the product's appeal in certain markets.

The problem

We needed to extend the value of Wolt+ to users just outside the free delivery range by introducing discounted delivery — while keeping the experience consistent across discovery, venue pages, and checkout.

Approach

As client DRI, I led the iOS implementation and contributed to the overall API and product design.

Key areas I focused on:

I also led discussions around API structure and naming, coordinating across teams to reach a solution that worked for both backend and client constraints.

Outcome

My role

Client DRI, leading implementation, RFC contributions, and cross-team coordination.
