AMBULA - Healthcare Booking Platform

Millions of people in India struggle to find the right doctor and book appointments easily. Many clinics still manage appointments through paper registers, phone calls, or WhatsApp. This creates inefficiencies: doctors lack a clear digital view of their daily schedule, patients carry physical files between consultations, and double-bookings happen frequently. The challenge: Build a platform that enables patients to search doctors by specialization, book appointments in under 2 minutes, and allows doctors to manage schedules digitally while preventing overbooking through concurrent . Process Started with user research to understand pain points. Designed the system architecture using MERN stack for scalability. Built RESTful APIs with proper database constraints for concurrent booking handling. Implemented frontend with React for smooth UX on mobile. Key decisions: Used backend database locks to prevent double-booking (not just frontend validation). Created separate dashboards for doctors and patients. Added real-time slot availability updates. Used JWT authentication for security. What didn't work: Initial frontend-only booking validation failed with concurrent requests. Switched to backend-level transaction management which resolved the issue.
