Thayna Santana
Product Designer
I came to design from front-end development, wanting to shape the why instead of executing the how. Now I design AI tools for hardware teams while shipping my own features and improvements via software.
Work Experience
Product Designer
Enzzo | Aug 2024 - Present | Seattle, WA
Design how people work with AI on a platform used by enterprise hardware teams including Resideo, Fluke, Tektronix, Arlo, Honda, and Ralliant.
- Built the interaction patterns the platform runs on, including the Quick Actions panel and the conversational question model that show users what to do next in context.
- Designed Enzzo Monitor, a new surface for competitive and market tracking, and handed engineering a spec complete enough to ship an MVP in a week.
- Ship design fixes straight to the codebase with AI coding tools when the built UI drifts from spec.
- Mapped what every AI action should produce, 100+ across six workspace areas, into one spec engineering builds against.
User Experience Designer
Thayna Santana Studio | Sep 2020 - Oct 2024 | Seattle, WA
Partnered with startups and established industries, delivering tailored product solutions from research through front-end build.

Business Integration Analyst | User Experience Engineer
Accenture | Jan 2020 - Jul 2020 | Houston, TX
Enhanced the SAP system for a renewable energy initiative, introducing new functionality that drove a 35% increase in internal process efficiency.

- Devised strategy with a 5+ stakeholder team to turn business needs into shipped products.
Selected Work
Design System and UX Writing System
Enzzo | 2025 - 2026
- Rebuilt the token structure so the design system survives contact with AI tools that generate and modify components.
- Wrote the product's UX writing standards as a spec the team actually uses, covering voice, error states, empty states, and confirmations across every surface.
Enterprise Onboarding Redesign
Enzzo | 2026
- Rebuilt the product's first-run experience as a 5-step conversational flow, shipped as two separate paths because clients arriving with mature process and clients arriving without it don't need the same thing.
