Ramona Bendias is a Founding Engineer specializing in applied machine learning with nine years of experience building practical ML solutions across startups and research institutions in the Berlin area. Trained as a natural scientist with an MSc in Data Science, she blends domain-driven curiosity with production-focused engineering—shipping models, data pipelines, and frontend/backend features in healthcare and AI products. At Kumo.AI and previously Workist she has driven ML projects from prototype to deployment, and her open-source contributions to PyTorch Geometric include adding the PNA model and work on explainability compatibility, showing a strong grounding in graph neural networks. Her bachelor research applied 3D MRI deep learning to Parkinson’s detection, an effort that honed her rigor around negative results and data limitations. Colleagues find her motivated by sustainable, environmentally conscious innovation and adept at turning theoretical knowledge into impactful code.
