As part of the 2023–24 redesign team, I contributed to transforming Kutxabank's app into a more intuitive and accessible experience. My focus went beyond visual updates: I worked on the foundations of the Design System, documenting it in a way that made adoption straightforward for the client's internal team, ensuring long-term consistency and scalability across the product.

The Design System covered typography, color palette, modular components, tokens and interaction patterns — all structured to support future product evolution. Alongside the deliverables, I led hands-on sessions to train the client's team on how to use and maintain the system, reducing dependency and empowering them to grow it over time. I also designed custom illustrations and testable prototypes that gave the app a distinctive visual identity and improved communication with end users at every touchpoint.

The redesigned Kutxabank app launched in September 2024 to strong results. Seeing a product reach millions of users — with a system built to last — is what makes this kind of project meaningful. The combination of solid foundations, clear documentation and team enablement meant the work didn't end at handoff: it gave the client everything they needed to keep building with confidence.
