Not just screens. Systems that hold up.

I’m Matías Sandoval, a product design engineer based in Quito, Ecuador, working with product teams across the US and Canada.

I design full-scope product UX and UI, and I build it as a system. Not just the screens, but the tokens, components and documentation underneath them, so the work holds up as the product grows and your engineers can build from it without guesswork.

That is the reason my practice moved toward code. I work from Figma through Cursor and Claude Code, which means a design system can arrive as a real component library and a deployed Storybook, not a file with a handoff note attached.

I hold a master’s degree in UX/UI, and I have been designing digital products since 2021.
