# Standing up a shared React system for a US healthcare team

Case 03 · Frontend architecture · Healthcare · Jordão Qualho, Senior Software Engineer

> A US healthcare product needed a shared React foundation and a delivery path. In a short advisory engagement, I built the component system, micro-frontend integration and baseline AWS/ArgoCD workflow.

Technologies: React, TypeScript, Storybook, AWS, ArgoCD, Micro-frontends

## Context

I worked through Tecla on a short advisory engagement for Sully, a US-based AI-assisted healthcare workflow platform.

## Problem

The team needed a consistent UI system and a deployable frontend architecture before a larger group could build on it.

## My contribution

- Built a reusable React component system using Atomic Design in a monorepo.
- Implemented early data views and micro-frontend integration.
- Set up baseline AWS infrastructure for FHIR-compliant healthcare workflows and automated CI/CD with ArgoCD.
- Aligned implementation directly with US-based healthcare stakeholders.

## Outcome

The shared frontend system and baseline infrastructure were in place. The client later discontinued the project after funding and team changes.

## What I learned

> Shared frontend infrastructure only creates leverage when teams can adopt it without losing autonomy.
