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

01

The right rendering strategy

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

02

A codebase that scales

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

03

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.

The network

One ice cube lifts the drink. An iceberg moves everything.

After more than 20 years in the business I have a network of senior specialists. When your problem needs more hands, I put together an A-team, hand-picked for you — from two people to a whole team.

  • Hand-pickedThe right skills for your problem — not whoever happens to be free.
  • ProvenSenior designers, developers and architects I have shipped with myself.
  • One contactI lead the team and answer for the result. You still talk to one person.
Build my team

How it works

Three steps. No surprises.

  1. 01

    We talk

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

  2. 02

    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. 03

    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.

Tell me where it hurts.

A few lines is enough. Tell me what you want to build, untangle or strengthen, and I reply personally within one working day.
