Project description
CareNest HMS centralizes patient records, scheduling, billing, and clinical workflows into a HIPAA-compliant platform that supports clinical staff and administrators with real-time visibility and audit-ready controls.
Challenges we tackled and how we handled them
Complex Patient Data Management - Implemented a layered data architecture using PostgreSQL for transactional data and Redis for session caching. We used Prisma for type-safe queries and enforced role-based access control so only authorized personnel can view sensitive patient records.
Real-time Appointment Scheduling - Built an optimistic-locking scheduling engine with WebSocket-based updates to avoid double-bookings and provide instant notifications across departments.
Audit-Ready Compliance - Developed logging middleware that captures full action context (user, timestamps, before/after states) to support on-demand audit reports and compliance workflows.
High Availability - Deployed the system on Kubernetes with auto-scaling, health checks, and a multi-region AWS setup for automatic failover to ensure near-zero downtime.

Problem Solving
Challenges We Tackled
Every project presents unique challenges. Here's how we approached and solved the key technical hurdles.
Complex Patient Data Management
Hospitals deal with massive volumes of sensitive patient data that must be instantly accessible yet securely stored with strict access controls.
Implemented a layered data architecture with PostgreSQL for transactional data, Redis for session caching, and Prisma ORM for type-safe queries. Role-based access ensures only authorized personnel can view specific patient records.
Real-time Appointment Scheduling
Managing doctor availability, room allocation, and patient preferences while preventing double-bookings across departments.
Built a real-time scheduling engine with optimistic locking and WebSocket-based updates. The system validates availability across multiple resources simultaneously and sends instant notifications on changes.
Audit-Ready Compliance
Healthcare regulations require complete audit trails for every data access and modification.
Developed comprehensive logging middleware that captures every action with timestamps, user context, and before/after states. Reports can be generated on-demand for compliance audits.
High Availability Requirements
Hospital systems cannot afford downtime as patient care depends on continuous access.
Deployed on Kubernetes with auto-scaling, health checks, and rolling updates. Multi-region AWS setup ensures 99.9% uptime with automatic failover.
