SymptomCare AI is a production-ready, full-stack MERN healthcare web application designed as an educational clinical decision-support and specialist triage platform.

Instead of generic web searches that trigger unnecessary patient anxiety or unconstrained chatbots that hallucinate fake diseases, this platform implements a Two-Tier Hybrid Triage Architecture:

🌟 Key Highlights & Engineering Features:

0ms Deterministic Emergency Safety Filter: Sub-millisecond regular expression layer that instantly detects acute red flags (crushing chest pain, stroke signs, severe respiratory distress, anaphylaxis) before calling external AI APIs.
Google Gemini AI Clinical Reasoning: Uses @google/generative-ai with structured JSON schema outputs (responseMimeType: "application/json") to evaluate duration, severity, age groups, and formulate interactive follow-up clarification questions.
11 Approved Medical Specialties: Validates AI outputs against hospital disciplines (Cardiology, Dermatology, General Medicine, Neurology, Pediatrics, Orthopedics, ENT, Gastroenterology, Pulmonology, Psychiatry, Gynecology) to prevent hallucinations.
Real Specialist Matching from MongoDB: Queries verified physicians with qualifications, consultation fees, clinic locations, and available OPD days.
1-Click Printable/Downloadable PDF Reports: Formatted @media print styling for outpatient clinical visits.
3 Distinct Portals: Dedicated workspaces for Patients, Doctors (OPD Desk), and Administrators (Analytics & Approvals).
1-Click Viva Demo Fill: Pre-configured demo logins on the sign-in page for instant university examination demonstrations.
