Four things worth knowing before we talk.
Based in Córdoba, Argentina, designing digital products across fintech, banking and SaaS, with startups and established companies in Latin America and the US. Currently at Banco de Córdoba, leading UX for corporate banking.
I help product teams find clarity in complexity and turn it into experiences that are intuitive, purposeful and built to scale, through UX strategy, interaction design and design systems.
Good design starts with understanding the problem, not jumping to solutions. I work closely with developers, ask the hard questions early, and care about systems thinking, because a great experience is never one screen.
I build working prototypes in Astro and Three.js using Cursor, Claude Code and Figma MCP. Instead of handing over static frames, I hand over something the team can open, click and test. Fewer handoff gaps, faster decisions.
Open to product design roles, remote or relocation.
