01 / Context

Picking App

GPA needed to digitize the picking process for its grocery e-commerce: a physically scattered operation with dozens of pickers working at once, a high rate of picking errors and constant pressure for speed. The existing app was slow and poorly suited to the routine on the floor.

02 / Contribution

Role within the professional track record.

A full UX process: in-store research with pickers, operational flow mapping, iterative prototyping and testing in real conditions. The focus was reducing friction: one-tap interface, visual hierarchy by order priority, real-time progress indicators. A product vision connected with operations and IT.

The next action has to be clear.

Three conceptual takes to present the theme of this work. The images, compositions and copy in this sequence are recreations, not materials delivered to the client.
