Jens De Neef

Web Application Engineer

I build web applications that are fast by default and maintainable at scale. My work sits at the intersection of technical architecture and developer experience — I care as much about the systems that produce software as the software itself.

Based in Belgium, working with teams across Europe on everything from greenfield platforms to legacy modernisation. I write about what I learn.
