Medcare - Doctor Appointment Web Application

Project Overview

This project was developed for the “Compete to Innovate: University Challenge with Ballerina”, organized by the IEEE Student Branch of the University of Moratuwa in collaboration with WSO2.

Many hospitals in Sri Lanka still depend on phone-based appointment systems, which are often inefficient, time-consuming, and error-prone. This project aimed to address that issue by developing a web-based doctor appointment management system to streamline bookings and improve patient experience.

Team & Collaboration

The project was developed by Team Code Ballerinas, consisting of four undergraduate engineering students.
I was primarily responsible for backend development, focusing on API design, authentication, and data management, while working closely with the frontend team to ensure smooth system integration.

Backend Implementation (Ballerina)

• Designed and implemented RESTful APIs using Ballerina
• Developed core backend features:
  • User registration
  • User login and authentication
  • Doctor appointment booking
• Used Ballerina HTTP services to enable reliable frontend–backend communication
• Integrated MySQL for persistent data storage

Frontend & System Integration

• React.js used for building a responsive and interactive frontend
• Tailwind CSS for a clean, modern user interface
• Seamless integration between frontend and backend services via REST APIs

Outcomes & Impact

• Successfully delivered a functional doctor appointment web application
• Demonstrated the suitability of Ballerina for backend service development
• Gained hands-on experience in full-stack system design, API development, and team collaboration
• Presented the solution as part of a competitive, university-level innovation challenge
