Build for Ambula '26

Millions of people in India still struggle to find the right doctor, book appointments easily, and maintain their medical records in one place. Many clinics continue to manage appointments through paper registers, phone calls, or WhatsApp messages. Doctors often lack a clear digital view of their daily schedule, while patients carry physical files from one consultation to another. Your challenge is to build a web platform that improves this experience for both patients and doctors. You have 14 days to complete the project. You are free to choose any technology stack. What matters most is that the platform works reliably, provides a good user experience, and demonstrates thoughtful engineering decisions. Answer These Three Questions Your solution should clearly demonstrate: Can a patient search for a doctor, view available slots, and complete a booking in under 2 minutes on a mobile device? Can a doctor log in, view appointments for the day, and add consultation notes and prescriptions after each visit? If two patients attempt to book the same slot at the same time, does only one booking succeed while the other user is shown the next available slot? What To BuildPatient Side Browse and search doctors by specialization and location Doctor profile showing: Name Specialization Available slots for the next 7 days Consultation fee Appointment booking flow: Select a slot Enter basic details (Name, Age, Phone Number) Receive a confirmation with a unique Booking ID Personal Health Summary: Blood Group Known Medical Conditions Current Medications This information should be visible to the doctor before the consultation begins. Doctor Side Secure doctor login Today's appointments dashboard showing: Patient Name Age Health Summary Post-consultation updates: Diagnosis Notes Prescription Slot Management: Block dates or time slots for leave and holidays Blocked slots should not appear to patients Platform RequirementsDouble-Booking Prevention Double-booking prevention must be implemented at the backend level, not only in the frontend. If two booking requests arrive simultaneously for the same slot, only one booking should be successful. Mobile-Friendly Experience The patient-facing application must work properly on mobile screens. This is a mandatory requirement. Technology Stack You may use any stack of your choice, including: MERN Django + React Flask Next.js Any equivalent combination Mandatory Submission Statement Include one sentence explaining: How you prevented double-booking at the backend and why your solution remains reliable under concurrent requests.
