Machine Learning Engineer | Stealth AI Start-up
Fine-tuned a Flux diffusion model with LoRA for multi-view character generation and built animation-pipeline components for shot reuse, scene consistency and model evaluation.
Raluca-Maria Sandu
AI/ML Researcher and Engineer · Zurich, Switzerland
I am an applied AI/ML engineer with around 20 years of coding experience, strong in communication, collaboration and mentoring . My industry work has mostly focused on visual AI, building systems that classify, understand, generate and reason about images and videos. During my PhD in Biomedical Engineering, I worked in European hospitals on medical imaging research for liver cancer, which led to journal publications and contributions to a commercial product deployed in hospitals. My current technical curiosity is physical AI: how machines can understand, navigate, and interact with our messy, beautiful 3D world. That interest also connects deeply with my life outside work: I love hiking, surfing, skiing, snowboarding, gardening, and birdwatching (currently taking ornithology classes). For me, AI is most exciting when it helps us perceive, understand, and protect the real world around us.
