Hello!

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

My expertise ranges from independently developing complex new features to leading legacy migrations. Combining a proactive, analytical, and solution-oriented approach, I optimize performance and implement comprehensive testing strategies. I am committed to clean code, user experience, and mentoring others through knowledge sharing. Driven by curiosity, I am also actively expanding my skill set toward full-stack development.

To keep my skills sharp, I dive into tech docs, YouTube channels, and other 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.
