For developing an application like Zomato or Foodpanda, a robust tech stack is crucial. Given your expertise in Java and Angular, a recommended stack would be using Java for the backend and Angular for the frontend. This combination is powerful for building scalable, secure, and dynamic web applications. Java provides a strong backend foundation with its reliability and performance, while Angular offers a comprehensive frontend framework for creating interactive user interfaces. This stack ensures a seamless integration between the frontend and backend components of your application, making it an ideal choice for your project.
