YouHeal Precision-Medicine Platform on Azure

Challenge pressure

A precision-medicine practice that reads genetics, epigenetics and biochemistry together needed one place where clients and practitioners work from those results, and an assistant that explains them without inventing anything.

The situation

YouHeal practises precision medicine, combining epigenetics, genetics and biochemistry with data science to find the root causes behind complex health problems. Lab results, questionnaires and genetic reports arrive from several sources, and practitioners need them turned into reports a client can read and questions a client can ask.

What we built

A React and TypeScript web app gives clients a portal and practitioners their own workspace, over a FastAPI platform API on Azure. Background jobs collect and read lab documents, run the analysis and draft reports, and scale down to nothing when idle. The AI health assistant uses Azure AI services with retrieval over Azure AI Search, grounded in the client's own reports, profile and the clinic's curated knowledge; answers stream live, and new documents are indexed automatically as they arrive. The infrastructure is defined in Terraform and deployed through GitHub Actions.

What changed

Clients ask about their own results and get answers drawn from their own reports, and practitioners decide which documents the assistant may use.

Constraints and decisions

Analysis and explanation are kept apart: rule-based engines produce every result, and the language models only retrieve, explain and draft reports for practitioner review, so no model can change a number. Access is role-based and every question to the assistant is logged.
