Challenge
In-store pickup already existed as a workflow, but it was slow, dependent on staff, and invisible to the customer until they were standing at the counter waiting. We wanted to turn it into something customers actively chose — fast, transparent, and ideally better than home delivery for the right use cases. The design challenge wasn't just the screens; it was choreographing a real-time exchange between an app in staff at busy store backstage (warehouse).
My Role
I led product design on the feature end-to-end across native iOS, Android, and adaptive mobile web — the in-app entry point, the live status model, push notification logic, the counter-number hand-off, and the web fallback. I owned the cross-platform consistency and the moment-to-moment customer experience.
Result
The pickup flow became one of the most-used post-purchase journeys in the app improving TNPS. Share of pickups initiated via app helps overal retention of customers towards mobile app. Feature serve as foundation for later picku-up box simillar UI flows.
Challenges
Two problems sat under that ambition. The first was awareness — even a well-designed flow doesn't change behavior if no one knows it exists, and in-app placement alone wasn't enough to shift a habit as ingrained as walking in and asking. The second was payments.
The pickup trigger depended on an API flag confirming the order was paid, but that flag traveled through several internal systems with their own timing and edge cases. Staff can't release goods on a "probably paid" signal, and customers can't trust a status that lags behind reality.
Purchase the Plan
Unlimited data, unlimited calls and messages — all in a simple flow. No need to visit a store or deal with unnecessary obstacles.
Purchase
Activate eSIM
A fully digital eSIM process. If you prefer eSIM, just select it and activate your plan right after completing the purchase.
Onboarding
Manage Subscription
You can control your spending for the upcoming month at any time. Cancel anytime. Upgrade to higher tiers or pause the plan when you don’t need it.
Subscription
Payment Flows
All payments are handled automatically — a new approach for Vodafone Czech, where payments were previously invoice-based and required manual customer action.
Payments
Final Design
By designing for self-service from the start — and letting user testing shape the flow rather than assumptions — we turned a purchase that used to require a sales rep into something customers can do on their own, in a few taps. The project also reinforced for me how much value comes from staying with a product from first concept through launch: the early decisions are the ones that shape everything downstream.
Enjoyable experiences
Whether browsing products in the Discover section, shopping for something specific, or picking up an order at a retail or delivery point — we designed UI flows to be intuitive and enjoyable for everyone.

Meaningful interactions
We crafted most user flows to align with familiar interaction patterns on Android and iOS. From smooth screen transitions to viewing products in AR within real environments — everything was designed to feel natural and engaging.
