Design and optimize database schemas, write SQL queries, and use ORM frameworks (e.g., Hibernate) for database interactions. Web Frameworks: Utilize Java frameworks like Spring, Spring Boot, or Java EE to build scalable and maintainable back-end systems. Implement RESTful APIs, handle HTTP requests, and ensure proper routing and authentication. API Integration: Integrate with third-party APIs and services to enhance application functionality. Implement API calls, handle responses, and process data from external systems. Security and Authentication: Implement security measures to protect application data and resources. Handle user authentication and authorization, implement secure communication protocols (e.g., HTTPS), and mitigate common security vulnerabilities.
