YouHeal: AI Health Assistant on Azure (Client Project)

Client project. Built by Van Data Team for YouHeal, a precision-medicine practice that combines epigenetics, genetics and biochemistry with data science. Live product: youheal.com

The practice needed one place where clients and practitioners work from lab results, questionnaires and genetic reports, and an assistant that explains them without inventing anything.

A React + TypeScript web app with a client portal and a practitioner workspace, over a FastAPI platform API on Azure

Background jobs that collect and read lab documents, run the analysis and draft reports, and scale to zero when idle

An AI health assistant on Azure AI services with retrieval over Azure AI Search, grounded in each client's own reports and the clinic's curated knowledge

Live streamed answers, with new documents indexed automatically as they arrive

Infrastructure in Terraform, deployed through GitHub Actions

Client portal, practitioner tools and an AI health assistant on Azure

AI answers grounded in each client's own reports, under practitioner control

Rule-based engines produce the analysis; the AI explains results but cannot change them

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. Access is role-based and every question is logged.

Stack: Azure, Azure AI Services, Azure AI Search, FastAPI, React, TypeScript, PostgreSQL, Terraform, GitHub Actions.
