Diagnose Core Web Vitals with field and lab data and produce an impact-ranked optimization plan. Use for slow pages, LCP/INP/CLS issues, or perf regressions.

Systematically test layouts across viewports, breakpoints, zoom, and orientation, then fix breakage. Use before shipping UI or when a layout breaks on a device.

Establish performance budgets: Core Web Vitals targets, bundle size limits, runtime budgets, and enforcement strategies.

Design and implement design systems: token architecture, component APIs, documentation patterns, and governance.

Audit crawlability, rendering, metadata, and structured data with evidence-backed fixes. Use for indexing problems, migrations, or pre-launch SEO checks.

Design ergonomic component APIs: prop design, composition patterns, accessibility defaults, and forward compatibility.

Design cohesive animation systems: motion principles, timing curves, choreography rules, and accessible motion.

Design micro-frontend architectures: module federation, route splitting, shared dependencies, and team boundaries.

Audit UIs against WCAG 2.2 AA and deliver prioritized, code-level fixes. Use when asked for an accessibility review, a11y compliance, or AT bug reports.
