I collaborated in the creation of a new in-store payment system combining the best of both offline and online worlds by allowing the user to pay through the app while in the store. I was responsible for the user research, creating & conducting the user interviews, as well as moderating the co-creation workshop with the client team. I was also responsible for the interaction & UX strategy, creating the strategy of the experience, the wireframes as well as the service blueprint and the journey. In order to reach a solution that would be easy to implement by Mango, we iterated the proposed solution with users in context, I was responsible for conducting this research as well as iterating the prototype, creating high fidelity prototype of the app as well as a deliverable functional prototype. The service has now been implemented in Mango stores across Barcelona and will be escalated worldwide.

Skills: UX Research, A/B Testing, In-depth interviews, Contextual interviews, Persona creation, iteration, high fidelity prototyping, Wireframing, User Journeys, Service Blueprints, Co-creation workshops.
