Senior🎓
Top SchoolGeoff Counihan is a pragmatic ML engineer with nine years of experience building production-grade models and data pipelines, currently driving ML infrastructure at Anyscale after leading GenAI and multilingual NER efforts at Mimecast. He’s deployed large-scale systems that process millions of emails weekly, built automated retraining pipelines (DVC/MLflow/SageMaker), and created LLM-powered explanation services using DSPy and Bedrock. Previously he led a data science team at SessionM/Mastercard, shipping 120+ models across regions and improving CLV classification with multi-task PyTorch models. Geoff blends hands-on engineering (ETL, deployment, visualization) with mentorship and architecture ownership, and brings a strong clinical-engineering background from MGH that informs his data-driven product decisions. Outside work he explores algorithmic trading with AI-in-the-loop and generates pen-plotter art, reflecting a curiosity for both quantitative systems and creative tooling.
