Healthcare Marketplace Platform

Overview
HelloMapper needed a scalable healthcare marketplace to connect patients with medical service providers across Australia. The platform had to handle sensitive health data, support real-time booking, and process secure payments — all while meeting Australian healthcare compliance standards.
The Challenge
The existing system was a monolithic application struggling under growing user demand. Response times were slow, the codebase was difficult to maintain, and adding new features took weeks. Payment processing was unreliable, leading to lost revenue and frustrated providers.
Our Approach
1
Decomposed the monolith into independent microservices for users, bookings, payments, and notifications
2
Built a React frontend with server-side rendering for fast initial loads and SEO
3
Designed a PostgreSQL database schema optimized for complex healthcare provider queries
4
Deployed on AWS with auto-scaling groups to handle traffic spikes
5
Implemented end-to-end encryption and audit logging for healthcare compliance
What Changed
Eliminated the bottleneck — each service scales and deploys independently
Payments now process reliably, ending the lost revenue from failed transactions
New features ship in days instead of weeks thanks to decoupled services
Platform meets Australian healthcare compliance requirements end-to-end
