04 / ABOUT

Curiosity
is the constant.

I’m Christian, a developer who likes building things that actually work.

From fullstack applications to Java tools and small browser experiments, I enjoy the point where an idea becomes something you can click, test and improve. I like digging into problems and learning along the way.
