Rovenma · PTT Kargomat
One system for every parcel locker, courier and customer
A parcel locker management ecosystem: a dashboard for PTTAVM, apps for couriers and end users, and the locker interface itself.

Overview
Making parcel management simple for everyone.
PTT Kargomat makes sending and receiving parcels simple and reliable. As the sole designer at Rovenma — a B2B company producing parcel lockers for e-commerce and shipping — I owned the UI/UX of the lockers and, with PTTAVM, designed the Kargomat management system and the apps for couriers and end users.
“I should be able to track every state of the parcel locker — production, status, installation and maintenance.”

Main goals
Three audiences, one ecosystem.
- Give PTTAVM one system to manage Kargomat locations, installations and deliveries.
- Help couriers find addresses quickly when delivering to a Kargomat.
- Keep customers satisfied at every step, from ordering to picking up.

Interviews
What every role needed.
I interviewed Kargomat users, PTTAVM couriers, Rovenma’s System Operator Manager and the maintenance team.
- End users want to pick up at any hour, and find the nearest Kargomat fast.
- The operator needs to track installations, full and empty lockers, and successful deliveries.
- Maintenance needs to see which lockers need repair or installation.
- Couriers need faster ways to identify locations.

Flows
Mapping every path through the system.
Separate flows for the locker itself, the end-user app, couriers and maintenance, plus the information architecture of the management system.



Design system
Gill Sans, PTT yellow and cyan, pixel-perfect icons.
A complete system covering typography, colour, desktop and mobile grids, icons, notifications, inputs, selectors, data visualisation, tables and modals — shared across the dashboard, apps and kiosk.








Final design
Dashboard, app and locker.
The management dashboard brings locations, users, utilisation, ratings, parcels and installations together; the mobile app guides people from sign-up to pickup; the locker touchscreen keeps every step big, linear and easy.
