Hello!

I'm Jonas Laurens, an Antwerp-based front-end developer with 6 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.
