Product Designer & Design Engineer from Buenos Aires, Argentina.
I take products from research to working code. I design in Figma, write the spec, and direct AI-assisted development (Claude Code) until the product is live and tested with real users. Every design decision is mine; the AI implements.
I focus on fintech and personal finance, accessibility (WCAG) and evidence-based design.
