Healthcare PWA Chat Integration
Challenge
A healthcare web application connecting clients and doctors was missing its core communication feature — a real-time user chat — with a hard deadline approaching. The existing codebase was a React PWA with a NestJS/Amplication backend, both lacking tests or quality gates. The client had no tooling strategy and needed both a technology recommendation and a full implementation.
Impact
The chat feature was delivered on time and fully integrated into the existing application. NestJS endpoints were covered with Jest unit tests — the first quality-assurance layer in the project. The solution kept user management centralised and real-time messaging performant through a direct WebSocket connection.
