Frontend Engineering
Build fast, accessible, beautiful interfaces with React, Next.js, and modern CSS.
Playbook: Rescue a slow frontend
Move a lagging app's Core Web Vitals into green without a rewrite.
React Patterns
Decide what renders on the server versus client in React Server Components to minimize JavaScript shipped.
Choose between local state, lifted state, URL state, and stores by asking who needs the data and when.
Treat non-happy paths as features: skeleton loaders, typed errors, retry affordances, useful empties.
CSS & Design Systems
Encode brand decisions as named tokens (CSS variables) consumed by utilities so themes change in one place.
Encode brand decisions as named tokens (CSS variables) consumed by utilities so themes change in one place.
Use fluid grids, container queries, and content-driven breakpoints instead of pixel-perfect mockups.
Animate with purpose: entrance choreography, micro-interactions, and reduced-motion respect.
Web Performance
Diagnose LCP, INP, and CLS from field data and apply targeted fixes per metric rather than guessing.
Modern formats, responsive sizes, lazy strategies, and priority hints for above-fold heroes.
Analyze, split, and replace dependencies so routes ship only the code they execute.
Accessibility
Combine automated scans with keyboard and screen-reader passes to find issues tools miss.
Native elements carry behavior and semantics for free; ARIA is the fallback, not the default.
Rendering Strategy
Static/ISR/SSR/streaming/client mapped to freshness needs, personalization, and TTFB budgets.
Worker pool sizing, transferable payloads, and Comlink-style RPC keeping UI at 60fps.
Journey Playbooks
Move a lagging app's Core Web Vitals into green without a rewrite.
Stand up tokens, primitives, and docs a team actually adopts.
Reach keyboard-complete, screen-reader-navigable flows on core journeys.
Mode selection documented, workers offloading measured hot paths at 60fps.
