Hello!

I'm Jonas Laurens, an Antwerp-based front-end developer with five years of experience crafting high performance, accessible web applications. Since falling in love with coding during an evening school course, I've specialized in modern JavaScript frameworks and bridging the gap between elegant UI/UX and robust engineering.

My expertise spans leading legacy migrations, optimizing performance via server-side rendering, and implementing comprehensive testing (Playwright/Vitest). I am committed to clean code, continuous learning, and mentoring others by sharing knowledge to help teams grow.

To keep my skills sharp, I dive into tech docs, YouTube channels, and industry media every day. When I'm not coding, I’m exploring the world with my wife and kids, playing guitar, or winding down with a good comic.
