Profile
A systems thinker who ships
I'm Karl Emmanuel Zoa — a Digital Consultant, Data & AI Engineer, and IoT Systems Engineer based in Berlin. I work at the intersection of data science, industrial technology, and business transformation.
My profile is deliberately cross-disciplinary: I can design an IoT sensor architecture in the morning, lead a stakeholder workshop in the afternoon, and review a model's F1 score in the evening. That versatility is not a compromise — it's a feature for complex, multi-dimensional challenges.
I've worked in logistics, manufacturing, agriculture, and food delivery — across Germany, France, Poland, and the Netherlands.
