Freelance React Developer in Hamburg
I'm Alexander Löhn, a freelance software developer based in Hamburg, Germany. I've spent roughly 5 years on medium-sized React applications using Next.js, Gatsby, and TypeScript — on top of 21 years of building for the web.
I like React for how explicit it is: issues surface early and are easy to debug. Recent React work includes the CMS-less website relaunch for Sorpetaler — a Gatsby and TypeScript site where editorial content lives in the repository and AI assists with content edits. No CMS, no license fees.

Frequently asked questions
- Do you take on remote React projects?
- Yes. I'm based in Hamburg, Germany, and work remotely for clients across Germany and Europe. On-site or hybrid work in and around Hamburg is also possible.
- React or Vue — which one should I pick?
- Both are excellent, and I've shipped production apps in each. Vue is my longest-running framework at 8 years; React is where I've spent the last 5. I'll recommend whatever fits your team and project — and I can work in either.
- What does your React stack look like?
- Next.js or Gatsby depending on the project, TypeScript throughout, Tailwind CSS for styling, and headless CMSs like Storyblok or Contentful when a CMS is needed at all.
- Can you take over an existing React codebase?
- Yes — that's a large part of my work. I use AI-assisted refactoring, testing, and documentation to modernize legacy code without stopping feature delivery.
- How quickly can you start?
- I'm available now for up to 30 hours per week. Reach out via email or the AI assistant on my homepage, and we can usually get started within days.
