react freelancer.
I'm Tobi Häfermann, a freelance React developer based in Bremen, Germany. For over ten years I've built large React and TypeScript applications, and I know both sides: employed in a team at a large IT service provider, and freelance for companies of every size, IT service providers and my own products.

frequently asked.
- What does a React freelancer do?
- A React freelancer is an independent developer who builds web applications and interfaces with React. Depending on what you need, I take on an entire product or reinforce an existing team, from concept to production.
- Do you work remotely?
- Yes. I work remotely with teams worldwide. On-site days in Germany, for a kick-off or workshops, are possible by arrangement. I'm based in Bremen.
- How much does a React freelancer cost?
- That depends on scope, duration and how we work together. I charge a daily or hourly rate. Tell me briefly what it's about and you'll get a concrete offer.
- How soon can you start?
- I'm currently at 90% capacity. For the right project I'll find a way; we'll clarify exact availability in our first call.
- Do you only do frontend?
- React is my focus, but I work across the whole stack: Node.js, Java, Rust and Python, plus Kubernetes, Docker and CI/CD.
- Freelancer or agency: which fits better?
- With me you get an experienced developer right inside your team, without overhead and with short paths. An agency makes sense when you need to fill many roles at once.
- Do you use AI?
- Yes, where privacy and contract allow it. Agents speed up implementation and testing. Architecture, reviews and responsibility stay with me.
