Project 02Data Quality / Observability

Sentinel

Healthcare Data Observability

The pipeline is green. But is the data healthy?

Sentinel explores how data pipelines can run successfully while silently delivering unreliable data, using synthetic healthcare records to investigate data quality and observability.

My role
Technical Lead & Data Engineer
Context
Data engineering observability project built on synthetic healthcare data.

Technology areas: Python · Synthea · FHIR · Cloud storage · PostgreSQL · Streaming · Data quality

Select a stage to explore

StreamStage 1 of 4

Generate synthetic healthcare records using Synthea and FHIR, then ingest them into a controlled data pipeline.
