The opportunity
TAPI is an Argentine wallet infrastructure company working with players like Lemon, Uala, Brubank, and Tarjeta Naranja. I was brought in to design a white-label wallet that could adapt to their clients' needs.
YPF became the first use case: Argentina's largest energy company aiming to launch a wallet for payments and loyalty, fully integrated into its ecosystem.
The challenge
YPF users lacked a unified digital wallet to manage payments, services, and loyalty points.
The product needed to enable bill payments (phone, internet, transport), balance top-ups, and rewards redemption within a single experience.
The timeline was highly constrained: less than one month to deliver a complete, development-ready design.
From insight to product
01 Extensive research: mapped end-to-end flows across leading wallets in Argentina, LATAM, and Europe (including N26) to identify best practices and simplification opportunities.
02 Simplified wallet experience: designed the wallet with a focus on minimizing friction, delivering some of the shortest flows in the market for bill payments, mobile top-ups, and transport card recharges (SUBE/RedBus).
03 Developer-ready design system: built a complete UI Kit and Design System that enabled developers to start implementing components before the final designs were fully completed.
04 Scalable white-label architecture: designed the system to be reusable and adaptable for multiple TAPI clients, not just YPF.
What I Learned
Speed without sacrificing quality: a deadline of under one month forced me to prioritize decisions and rely on research-backed patterns. The Design System became the key multiplier for speed.
Research as a competitive advantage: mapping 10+ wallets gave me a solid foundation to make fast, informed design decisions instead of iterating blindly.
Designing systems, not screens: thinking in terms of white-label from the start changed my approach. Every component needed to be flexible enough to work across different brands.
Aligning design with infrastructure: working directly with the TAPI team taught me to design with the constraints and capabilities of the existing infrastructure in mind.
