Ciarán Ryan

I'm an AI Engineer at the Government Digital Service, where I work on Gov UK Chat — integrating LLMs, building RAG evaluation pipelines, and designing agentic architectures for public services.

Previously at Publicis Sapient, I led data science across audience segmentation, graph ML recommendation engines, and multi-agent prototyping for executive decision-making.

I hold a First Class Honours MA in Statistics from University College Dublin and I am a Google Certified ML Engineer & AWS Certified AI Practitioner. I'm interested in how agentic workflows and LLMs can be applied responsibly at scale.
