Motion and interaction design skill using interpretive lenses informed by publicly available work from Emil Kowalski, Jakub Krehel, and Jhey Tompkins. Two modes: build interactive components with purposeful motion, or audit existing animations to catch AI-generated motion anti-patterns. Use when creating, adding, animating, or reviewing UI motion: transitions, hover states, micro-interactions, enter/exit animations, or motion design work in React, Framer Motion, CSS, or HTML. This skill is not authored, reviewed, or endorsed by the referenced designers.
Audit frontend websites and apps before launch. Use for production-readiness reviews, visual polish checks, responsive QA, accessibility risks, performance and SEO basics, interaction states, forms, media, copy clarity, trust signals, and ship/no-ship recommendations for React, Next.js, static sites, dashboards, landing pages, portfolios, and product UI.
GSAP performance guidance — prefer transforms, avoid layout thrashing, use will-change selectively, and batch animation work. Use when optimizing GSAP animations, reducing jank, or when the user asks about animation performance, FPS, or smooth 60fps.
Audit website accessibility. Use for semantic structure, headings, alt text, forms, focus states, keyboard navigation, color contrast, labels, ARIA misuse, reduced motion, captions, skip links, modals, menus, carousels, and final frontend QA aligned with WCAG-style accessibility expectations.
Improve website accessibility and performance polish. Use for semantic HTML, keyboard navigation, focus states, contrast, alt text, reduced motion, image/video loading, canvas fallbacks, bundle caution, animation performance, and final production readiness for polished websites.
Define animation easing language for premium websites and apps. Use for motion timing systems, easing curves, spring feel, duration scales, stagger rhythm, delay strategy, entrance/exit timing, tactile controls, cinematic sections, and translating luxury, modern, fast, calm, or playful motion words into concrete values.
