DoctorTracker

DoctorTracker is a full-stack clinical management portal engineered for healthcare coordinators to streamline physician assignments, monitor patient admissions, and track facility-wide clinical trends in real time. Built with Next.js 16 (App Router), React 19, TypeScript, and Express 5, the system couples a high-density clinical dashboard with a decoupled REST API backend backed by MongoDB and Mongoose.

On the backend, analytics queries across physician caseloads, monthly admissions trends, and diagnostic distributions are consolidated into a single MongoDB $facet aggregation pipeline, executing multi-faceted metrics in parallel in a single database roundtrip. To eliminate costly $lookup table joins during high-throughput directory pagination, doctor documents maintain an atomic patientCount field synchronized via MongoDB $inc operators on patient lifecycle events. On the frontend, table filter states, specialties, and pagination parameters synchronize bidirectionally with URL search parameters (with debounced search inputs) to preserve browser history and deep-linking, while Recharts visualizations use client-mounted hydration guards to prevent SSR mismatch layout shifts.
