The problem

Hospital departments had no real-time visibility into equipment — manual tracking caused wasted searches, double-purchasing, and unplanned downtime.

What I built

Real-time equipment tracking with Socket.io, status monitoring, intelligent allocation, and a GraphQL API — cutting equipment discovery time by 40%.

Core features

• -Real-time tracking dashboard with Socket.io live updates
• -Status monitoring — available, in-use, charging, maintenance
• -Department-based allocation and requests
• -Maintenance schedule tracking and alerts
• -Equipment history and audit trails

Engineering highlights

• -Full-stack architecture from database to real-time UI
• -Distributed real-time system via Socket.io clusters
• -GraphQL query optimization with DataLoader batching
• -Redis caching layer reduced DB load by ~60%

Tech stack

Impact

• -40% reduction in API response time
• -Sub-second equipment status updates
• -Eliminated phantom equipment purchases via data-driven allocation
