Data Engineer · Developer · Creator
Hi, I'm Marcel-TO
I turn passion into software - building data pipelines, open-source tools and the occasional experiment. This is my corner of the web for projects, writing and ideas.
Who I am
I build things at the intersection of data, code and curiosity.
Always chasing the next challenge - whether that's a gnarly data problem, a new language, or a side project that refuses to leave my head.
