Hire a senior Next.js developer who fixes the caching model
Next.js 16 App Router, React 19, RSC, Cache Components, Vercel-native deploys. One senior engineer. Fixed monthly price.
Who this is for
Founder shipping on Next.js App Router who needs senior help with RSC, caching, and Vercel cost.
The pain today
- The App Router rewrite stalled halfway.
- Hydration mismatches, suspense boundaries misbehaving, Lighthouse is red.
- Nobody on the team knows use cache versus unstable_cache versus revalidatePath.
- Vercel bill is climbing and the caching model is a mystery.
The outcome you get
- A senior Next.js engineer shipping Next 16, React 19, and TypeScript in production.
- A caching strategy that actually lowers Vercel cost.
- App Router migration finished or deferred with reasoning.
- Fixed monthly price, 14-day money-back, daily async updates.
Next.js 16 work I actually ship
Current Next.js delivery runs on Next 16, React 19, TypeScript 5, and Tailwind 3 or 4. The work includes App Router routing and layouts, Server Components plus Client Components boundary decisions, Cache Components and the use cache directive, Server Actions, middleware and proxy routes, OG image generation, streaming and Suspense, ISR versus PPR versus on-demand revalidation, and Vercel edge versus node runtime selection. I deploy on Vercel by default (Instill runs this stack) and on AWS behind Cloudfront when the team requires self-hosting. Performance and Core Web Vitals are a baseline requirement — not a follow-up ticket.
Two live Next.js products to point at
Instill is a self-initiated AI skills platform running Next.js 16 plus React 19 plus PostgreSQL plus Vercel plus MCP Protocol. It has 30+ active users, 1,000+ skills saved, and 45+ projects powered. It is the first AI case study I have shipped as a standalone product, and every Next 16 feature in the release notes lives in the codebase (RSC, Cache Components, PPR where useful). Imohub is a real estate portal running Next.js plus Laravel plus MongoDB plus Meilisearch plus AWS — 120k+ properties indexed, under 0.5 second queries, top-3 Google rankings, and roughly 70% infrastructure cost cut versus the prior stack.
Vercel caching and cost — where most teams lose money
The single biggest reason Next.js Vercel bills climb is not traffic. It is caching misconfiguration. Client components fetch on every render. Server components forget to declare cache lifetimes. revalidate stays at the default 0. edge runtime gets picked for work that should be on node. Server Actions trigger full page revalidation on every mutation. When I start a caching audit the first pass usually cuts function invocations by 40 to 60% without touching traffic. The second pass tunes Cache Components and cacheTag so revalidation is surgical rather than nuclear.
Pricing and engagement shape
Applications subscription is $3,499 per month flat. 2 to 4 day delivery cycles, 2 to 3 clients at a time, daily async updates via Linear or Jira, weekly 30-minute call. 14-day money-back in the first two weeks, then cancel anytime month to month. Typical Next.js engagements run 4 to 16 weeks depending on whether this is a greenfield build, an App Router migration, or a rescue. Work Made for Hire — every commit is yours from day one.

Frequently asked questions
The questions prospects ask before they book.
- Which Next.js versions have you shipped?
- Next.js 12 through 16. Current work is Next 16 with React 19. I have migrated apps from Pages Router to App Router on Next 13, 14, and 15.
- Do you deploy on Vercel only?
- Vercel is the default (Instill, this site). Self-hosted on AWS plus Cloudfront is available when policy or cost requires it. Cloudflare Pages and Netlify are adjacent and supported.
- Can you finish an App Router migration?
- Yes. I have done Pages to App migrations on mid-size apps. The deliverable is a migration plan with phases first, then execution. Most teams stall because nobody owns the caching rewrite — I own that piece.
- Do you handle SEO and Core Web Vitals?
- Yes. LAK Embalagens ships top-3 Google rankings and a 45% bounce rate reduction on a Next.js corporate site. SEO baseline (metadata, sitemaps, structured data, image optimization, JS budget) is part of every Next.js delivery.
- RSC vs Pages Router SSR — how do you choose?
- RSC by default on new projects. Pages Router SSR only when constrained by a library that has not updated or when the team explicitly needs to stay on Node-only runtime. The decision is written into the delivery plan.
