I'm a Senior Engineer in Medical Data Engineering, working at the intersection of healthcare data, AI agents, and production data platforms.
My work focuses on:
- Building and optimising large-scale clinical data pipelines with Python, Nextflow, SQL, Bash, Docker and AWS
- Standardising healthcare data into OMOP CDM and FHIR, including data from HL7 v2, Epic and clinical/research datasets
- Developing terminology and concept-mapping workflows using SNOMED CT, ICD, Athena/OHDSI and related biomedical vocabularies
- Building LLM-powered and agentic workflows for healthcare data, including prompt engineering, tool use, evaluation and observability
- Developing MCP servers and tools to connect AI agents with biomedical and clinical data services
- Using Langfuse for LLM tracing, evaluation, prompt management and workflow observability
- Designing data-quality, profiling, validation and source-to-standard transformation systems
I have a PhD in Cognitive Neuroscience and Neuroimaging, with research experience across functional MRI, structural MRI, EEG and clinical data.
