Senior🎓
Top SchoolDimitris Poulopoulos is a Senior Machine Learning and MLOps Engineer with 11 years of experience designing and scaling Kubernetes-native AI platforms and production ML workflows. He combines deep expertise in distributed training, LLM fine-tuning (PEFT, RLHF, DPO), and model optimization with hands-on automation of Kubernetes deployments and CI/CD for hybrid and multi-cloud environments. An active Kubeflow contributor and former core developer on the widely used Kale project, he bridges data scientist ergonomics and production reliability by implementing model serialization and multi-framework support (TF, PyTorch, XGBoost). At Mozilla.ai he helps make open-source LLM evaluation tooling mainstream, building on prior roles at HPE and Arrikto where he integrated NVIDIA inference stacks, RAG systems, and vector DBs. He mentors engineers, holds advanced research experience from a PhD-track role, and is known for translating research-grade ML into robust, maintainable infrastructure.
