Foundation - The why
"Streamlining" — making device purchases, upgrades, and plan refills simple.
The vending machine app was designed to transform the way customers access devices, plans, and SIM kits. The objective was to reduce friction in the purchase process, enhance convenience, and provide a reliable self-service experience in a physical retail context.
This project required collaboration across product, engineering, and operations teams to design a solution that was intuitive for users while adhering to technical feasibility and operational constraints.
As the Lead Product Designer, I drove the project from requirement gathering to design conceptualization, UX/UI, research, and post-delivery maintenance — ensuring the product was both functional and enjoyable to use.
