Johnathan Verstraaten

Freelance Web Developer

Hey there! I'm Johnathan, a 17-year-old self-employed web developer from the Netherlands and Ghana, and currently enrolled in the Informatics Systems course at Vytautas Magnus University.

I discovered programming in early 2020, and since then I've built up skills in web development, mainly front-end with React and Astro, but also some backend using Node.js.

Outside of coding, I'm also into wildlife photography. You can check out some of my work on my photography site.
