React developer
in Amsterdam
I'm Sander, a senior freelance React & Next.js developer in Amsterdam, available on-site or remote across the Netherlands and Europe. Full-stack engineer (NestJS, Java), with my focus on the front-end. Startups hire me to build their MVP, strengthen their team or fix a codebase that's slowing them down. I have an eye for UI and UX, and with Claude Code in my daily toolchain I ship faster than a solo developer could a few years ago. You talk directly to me and I write the code, with no agency in between.

Three ways
I help
Senior firepower for your team
A senior developer who onboards in days and ships from the first week. I join your standups, your repo and your Slack, on-site in Amsterdam or remote.
Codebase rescue
Slow pages, risky deploys, a previous developer who left. I start with an audit, then fix the things that block your roadmap: performance, stability and tech debt.
He created impact by completely setting up a new front-end for a service that is used by 100+ internal users, well within the deadlines. I can truly recommend Sander if you need a really good FE engineer with the right attitude. He is the first I will call when I've got another assignment for him.
How it works
- Step 1
Intro call
30 minutes, free. You explain what you're building and what you need. I'll tell you honestly whether I'm the right fit, and if I'm not, I'll point you to someone who is.
- Step 2
Written proposal
Scope, timeline and cost in writing. Fixed price for scoped projects, a day rate for embedded work.
- Step 3
Ship weekly
Working software every week, deployed somewhere you can click through it. Short feedback loops keep the project on course.
- Step 4
Clean handover
Documented code, typed APIs and a walkthrough for whoever maintains it next, so the project doesn't depend on me forever.
Questions
founders ask
What does it cost to hire a freelance React developer?
I work on a day-rate basis for team engagements and fixed proposals for scoped projects like MVPs. After a free intro call I send a written proposal with the timeline and cost, so you know what you are committing to before we start.
How fast can you start?
Typically within one to two weeks, depending on my current engagement. For codebase rescues and short audits I can often start sooner. Current availability is always listed on the contact page.
Do you work on-site in Amsterdam?
Yes. I'm based in Amsterdam and happy to work on-site or hybrid with teams in the area. For clients elsewhere in the Netherlands or abroad I work remotely, with overlap on CET hours.
Can you build our MVP on your own?
Yes. I'm a full-stack engineer with a front-end focus: Next.js, TypeScript and Node.js or NestJS, from data model to deployed product. At Bol.com I also wrote backend-for-frontend services in Java and Kotlin. Recent solo deliveries include complete platforms and storefronts, see the work page for examples.
Do you also do the design?
For most projects, yes. I design the UI/UX myself, from wireframe to final interface, and I'm equally comfortable building from a designer's Figma when there is one. I also build SEO landing pages: fast, structured for search engines and measured on Core Web Vitals.
Do you use AI tools like Claude Code?
Yes, daily. Claude Code writes a lot of the boilerplate, while the architecture, code review and product decisions stay with me. It means one senior developer can move at the speed of a small team. Everything that ships is reviewed, typed and tested. This website is an example: designed and built with Claude Code, and it scores 100 on Lighthouse.
Why hire a freelancer instead of an agency?
With a freelancer, the person you speak to is the person who writes the code. You get direct communication, one accountable developer and far less overhead than an agency.
Do you take over existing codebases?
Often. Performance rescues, stalled rewrites, and 'our previous developer left' situations are a regular part of my work. I start with a short audit so you know exactly what you're dealing with before committing.
