Product Designer at AntBills, shaping a mobile-first family finance platform with reusable design systems and implementation-ready flows.

Message

At AntBills, I designed a mobile-first family finance platform end to end, translating the product problem into information architecture, flows, prototypes, and implementation-ready specifications.

I structured journeys across onboarding, dashboards, goals, commitments, cards, simulations, and financial decisions, defining roles, states, errors, and alternative scenarios. I also created a Design System with reusable components and interaction patterns.

At Dos al Cubo, I transformed resolution-specific layouts into a unified responsive template system, reducing design and implementation time by more than 40%. I built reusable Figma components and adapted the system to an internal AI tool.

Earlier, I designed a mobile-first web platform at iGaming Exhibition and e-commerce experiences for five banks at Aper. I worked with Engineering to make responsive interfaces feasible while balancing usability, commercial goals, and visual consistency.
