Hi there, I'm Koen! 👋🏼

I'm a passionate & entrepreneurial JavaScript developer from the Netherlands who likes to push the web beyond it's limits. I specialize in modern frontend using React & Svelte and I also feel at home on the backend using Node/TypeScript. I'm interested in helping inspiring companies create innovative web apps that users love.

You can also find me on LinkedIn and Twitter.
