1. Real-Time Booking System (Node.js, MongoDB): The backend is built using Node.js, while MongoDB handles dynamic data storage for venue availability and user bookings. This setup ensures real-time data synchronization for seamless venue reservations and activity scheduling, enabling users to instantly book and manage their activities.

2. Personalized Recommendations (Machine Learning, Python): GoPlay uses machine learning algorithms implemented in Python to analyze user preferences and activity history. This data is used to provide personalized venue and activity recommendations, enhancing user engagement and overall experience.

3. Scalable Cloud Infrastructure (AWS, S3, EC2): The app is hosted on AWS, with EC2 handling server load and S3 storing user-generated data, such as booking history and venue information. This ensures the app can scale efficiently as the user base grows, while maintaining fast response times and data reliability.
