I design and build design systems — the token, component, and tooling layer that lets product teams move fast without design and code drifting apart. My work spans Figma system architecture, design-to-code pipelines (Code Connect, tokens, component libraries), and increasingly, AI-assisted workflows for extracting and generating design systems from existing codebases.

• Design systems at scale — building the single source of truth (tokens → components → docs) that a small systems team uses to support a much larger product org
• Figma ↔ code alignment — Code Connect, design linters, and prototyping libraries that keep design and engineering representations honest with each other
• Design tooling — Figma plugins and internal tools that remove manual, repetitive work from design workflows
• AI-assisted systems work — using AI + Figma's tooling to reverse-engineer UI from codebases that have no design reference, and to accelerate component library generation

• Meta — Reality Labs Design System: token/component/documentation foundation for Meta's VR platform, including Code Connect, a design linter, and a prototyping library
• Meta — Horizon Mobile Design System: rebuilt the design system powering the Horizon mobile app on iOS/Android; drove 80% of legacy components deprecated in production within 3 months of the front-end work landing
• Meta — Horizon Worlds UI Refresh: token schema, component library, and spec set for the 2D panel UI rolled out across every world on the platform
• Google — Android 14: consolidated a fragmented design system into a single Figma source of truth and restructured the Android team's Figma org for better cross-functional distribution
• Splunk Mobile: stood up Splunk's first mobile design system, shipped publicly on iOS and Android within a year
• Airbnb — Air/shots: internal tool for previewing the Airbnb app across every device, platform, and language — used by thousands of internal designers
• Anduril — Mini Lattice Design System: self-directed project extracting a component library from an open-source app with no UI reference, using AI + Figma tooling, wired to GitHub with a runnable dev environment
• Tutorial Tim: my own UX/UI and Figma design-systems education platform — 5,000+ students, 6,400+ YouTube subscribers, freeCodeCamp partnership
