👤
Senior🎓
Top SchoolMarius Hamacher is an AI solutions specialist and founder with a decade of hands-on experience building NLP systems, data annotation platforms, and ML-driven tooling from research prototypes to production. He combines academic rigor—an MS in Applied Cognitive and Media Science with distinction—with practical delivery, having led projects for hate-crime detection, self-updating FAQ systems, and annotation quality libraries. As CTO of Heph Technologies and in roles at HUMAN Protocol and universities, he blends product-minded system design with low-level implementation (including NumPy-from-scratch algorithms) and rapid prototyping. He is comfortable moving between research, engineering, and client-facing solution design, often extending annotation systems to novel text use cases. Based in Düsseldorf, he brings a pragmatic curiosity and a track record of turning complex evaluation problems into reproducible, deployable tools.
