Next.js & React · Stockholm

A Next.js and React consultant who has built it for real.

I built and run my own SaaS product on Next.js, from the first commit to paying users, and introduced Next.js and React at H&M and Legora. App Router, server components, SSR and SSG, monorepos with shared types. Not theory, production.

What you get

  • The right rendering strategy

    Server components where they bring speed, client where they bring interaction. You avoid both slow pages and needless complexity.

  • A codebase that scales

    Monorepo with Turborepo, shared schemas, a typed API client from OpenAPI. The same patterns that keep large teams aligned.

  • Migration without a stop

    From Create React App, Pages Router or an old framework to Next.js, step by step, while the site keeps working.

How it works

Three steps. No surprises.

  1. We talk

    Thirty minutes. You tell me where it hurts, I listen and ask the questions that usually decide things.

  2. I draw the plan

    What gets built, in what order, and what it costs. On one page, so everyone in the room understands it.

  3. We build

    Short cycles. Real code in production early. You see progress every week, not at the end.

Common questions

Common questions about next.js and React consultant

Do we need Next.js or is React enough?

If you need SEO, fast first paints or server logic close to the interface, Next.js is right. If it is a logged-in application behind authentication, React is often enough. I help you choose without selling you more than you need.

Can you migrate our existing React app to Next.js?

Yes, incrementally and without downtime. First what matters most, usually the pages that need to be found in search.

What does a Next.js consultant cost?

Hourly or fixed price. Clear quote before we start. Colleagues abroad can take parts of the work when the budget calls for it.

Vercel or self-hosted?

Both. Vercel when it fits, Docker on Railway or Azure when you want to own operations. I run products on both.
