About me
I turn messy data
into systems that decide.
I’m a data scientist and applied AI engineer at the Ontario Ministry of Children, Community and Social Services, where I build RAG systems, knowledge graphs, and NLP pipelines that help caseworkers find answers faster and make sense of complex records.
Most of my work sits at the intersection of data engineering and applied machine learning — building the pipeline, then the intelligence layer on top: LangChain/LangGraph agents, Neo4j graph-RAG, entity resolution, and document intelligence with Azure AI Form Recognizer.

Different craft.
Cobble StudioWoodwork · Toronto
Away from the screen, I work with wood. At Cobble Studio, I make everyday objects with a focus on form, texture, and how they feel in the hand.
Mugs, scoops, spoons, clips, and plates — made to be used, every day.
