Freelance Next.js developerAvailable now

A freelance Next.js developer who stays after the launch.

I build and maintain production Next.js applications for product companies and funded startups: customer portals, dashboards, SaaS products and marketing sites that have to hold up under real traffic. TypeScript throughout, deployed on Vercel or your own infrastructure.

Is this a fit?

An honest fit check before we talk

I would rather tell you no on the first call than waste your budget. Here is what a good match looks like for this kind of work.

A good fit if

  • You are building a web product on Next.js and need a senior developer to own it end to end.
  • You have a Next.js app in production and want someone who can ship features and keep it healthy for years.
  • You want to move from Pages Router, Create React App or a legacy frontend to the App Router without stopping releases.
  • Your team needs senior Next.js capacity now, not after a three-month hiring process.

Probably not a fit if

  • You want the cheapest possible hourly rate.
  • You need a full agency with design, marketing and a team of developers.
  • Your stack is far from TypeScript and React, for example .NET MVC or Django templates.

What I do

What the engagement typically covers

New Next.js applications
Architecture, data fetching, authentication, forms, payments and integrations. App Router, Server Components and Server Actions where they help, and a simpler setup where they do not.
Feature work on existing apps
I join your repository, read the code before I change it, and ship features in short iterations with a weekly written update.
Migrations and upgrades
Pages Router to App Router, JavaScript to TypeScript, CRA or Gatsby to Next.js, major version upgrades. Done incrementally so releases never stop.
Performance and Core Web Vitals
Rendering strategy, caching, image and font loading, bundle size. Measured before and after, not guessed.

Process

How we'll work together

The same four steps for a two-day fix and a two-year engagement.

  1. 01

    Intro call

    A free 30-minute call where you tell me about your project, goals and constraints. I ask a lot of questions and tell you honestly whether I'm the right fit.

  2. 02

    Proposal & estimate

    You get a short written proposal: scope, approach, timeline and price. Fixed price for well-defined projects, hourly or retainer for ongoing work.

  3. 03

    Build in the open

    Short iterations, working software early, and a weekly update you can actually read. You see progress and can change course before it gets expensive.

  4. 04

    Launch & support

    I handle deployment, hand over clean documentation, and stick around for support and further development if you want me to.

FAQ

Questions I get asked

Which Next.js versions and features do you work with?
Current Next.js with the App Router, React Server Components, Server Actions, route handlers and the Metadata API, as well as older Pages Router codebases that need maintaining or migrating. This site runs on Next.js 16.
Can you also build the backend and APIs?
Yes. I am full-stack: Node.js, REST APIs, SQL databases, authentication, payments and third-party integrations. For many products the backend lives inside the Next.js app itself.
How quickly can you start?
I keep my availability status up to date on the homepage. If it says available, I can usually start within one to two weeks. The first step is a free 30-minute intro call.
How do you price work?
Fixed price for well-defined projects, hourly or a monthly retainer for ongoing work. My preferred engagement is 20-40 hours a week for six months or more. Rates are in the proposal, not on the site, because they depend on the scope.
Is one developer a risk for us?
Code lives in your repositories from day one, written so the next developer can pick it up. Documentation and handover are part of every engagement, not an extra. My track record is long tenures, which is continuity, not dependency.
Do you work with companies outside Denmark?
Yes. Most of my work is remote. I am in the Central European timezone, which gives full overlap with Europe and the UK and 3-6 hours of overlap with the US East and Central timezones. I work async-first with a written weekly update.
