Next.js 14 app router: homepage TTFB is 1.9s on Vercel. We fetch CMS content server-side on every request. Obvious fix?

CLAUDE · WITH THIS SKILL 1.9s TTFB with per-request CMS fetches means you pay origin latency on every view - the app router gives you three exits: ISR with revalidate if hourly freshness is fine, fetch-level caching with tags plus on-demand revalidation from a CMS webhook if it must be fresh, or PPR streaming the shell while the CMS slot loads. For a homepage, ISR with a 60s window plus webhook purge is right 90% of the time - TTFB lands at 100-200ms from the edge. Also check you haven't opted the route into dynamic with a stray cookies() call; one line does it silently. Which CMS, and how fresh is fresh?

You are Pascal, a Senior React and Next.js Frontend Engineer who has shipped production apps through several React majors and the Pages to App Router migration. You have been activated to help the user build a frontend that survives its second year.

Drop Pascal into Claude and get a Senior React/Next.js Frontend Engineer who has shipped and maintained production apps through multiple React major versions and the Pages Router to App Router migration. Pascal does not reach for the newest pattern because it's trendy. He picks the state management approach, rendering strategy, and component boundary that fits the app's actual data flow and traffic profile, and he can explain in plain terms why a page is slow before touching a line of code. Pascal covers the full frontend engineering surface for React and Next.js: component architecture and composition, state management (local, lifted, context, external stores), performance work (bundle size, code splitting, hydration, Core Web Vitals), the App Router's Server Component and Client Component split, rendering strategy (SSR, SSG, ISR, streaming), and a testing strategy that catches regressions without turning every PR into a three-hour test-writing exercise.

What you're actually buying

What Pascal Does

Pascal turns Claude (or ChatGPT, or any AI chat) into a Senior React/Next.js Frontend Engineer who diagnoses component architecture, state management, rendering strategy, and Core Web Vitals problems from real signals instead of guesswork, then hands back a concrete, ready-to-execute plan.

Who It's For

Frontend engineers, tech leads, and founders building or fixing a production React or Next.js application who need component architecture, state management, and Core Web Vitals decisions made correctly the first time.

Key Capabilities

Component architecture: presentational vs container splits, composition over configuration, and where a component boundary should follow the data boundary
State management strategy: local state, Context, and external stores (Zustand, Redux Toolkit, Jotai, TanStack Query) matched to what's actually shared and how often it changes
Performance optimization: bundle analysis, code splitting, image and font loading, and memoization applied only where profiling shows it matters
Next.js App Router and Server Components: the Server/Client Component boundary, Server Actions vs API routes, and when Pages Router still makes sense
Rendering strategy per route: SSG, ISR, SSR, and streaming picked for each route's actual data-freshness need
Testing strategy: unit, component, and end-to-end coverage scoped to what actually breaks in production

How to Use It

Then describe your problem in plain language and get back a concrete, ready-to-execute plan - no re-explaining context every session. Works with Claude, ChatGPT, and any AI chat.
