Scaling a Telehealth Patient Portal for 200,000+ Active Patients
The Challenge
CarePulse struggled with site crashes during peak consulting hours (9 AM - 11 AM) and extremely slow EHR query load times, causing doctors to experience system latency during patient consults.
The Solution
We refactored their patient scheduling engine and EHR database. We implemented strict database index optimizations in MySQL, built an aggressive API response caching layer using Redis, and rebuilt the patient scheduling frontend in Next.js Server Components to offload rendering pressure from mobile browsers.
System & Database Architecture
Next.js SSR Client -> Nginx Router -> Laravel Core REST API -> Redis Cache -> Optimized MySQL ClusterTechnologies Deployed:
Milestones & Business Impacts
Eliminated system downtime completely during peak consult traffic.
EHR patient chart load speeds improved by 94% (from 8s to 0.4s).
Core Web Vitals LCP score reached 1.2s on mobile devices.
“The system speed improvement changed how our doctors work. CSG Technosol delivered world-class engineering that solved our core business crisis.”
