Data Architect at Pfizer designing the data layer behind an agentic AI platform.
United KingdomWhat I'm looking for
At Pfizer, I own the data layer behind an agentic AI platform, from business requirements to a traced answer. I designed the layer for SAP-sourced data and write logical and physical models, maintain the data dictionary, and define data quality measures.
At NN GROUP, I designed a new device and identity data service on Azure Databricks. I produced its conceptual, logical, and physical models, wrote the Data Architecture and Governance Plan, and got the designs approved at the architecture forum.
At INSY2S, I led client engagements to design Azure data platforms, deployed Databricks and Azure services with Terraform, and trained data professionals in data architecture. Earlier, I modelled regulated healthcare, utilities, and investment data, and designed reporting and warehouse architectures across banking, insurance, public services, and other sectors.
I work across data architecture, modelling, governance, and delivery, supporting engineers and analysts from ingestion design through deployment. I'm Databricks Data Engineer Associate and SnowPro Core certified, and I'm available immediately for remote contract engagements.
