2. Web Frameworks:
- MVC Architecture: Familiarity with Model-View-Controller (MVC) frameworks like Django (Python), Ruby on Rails (Ruby), Spring Boot (Java), or Express.js (Node.js).
- Rapid Development: Ability to leverage frameworks to expedite development while maintaining code quality.
3. Databases:
- Relational Databases: Proficiency in working with relational databases like MySQL, PostgreSQL, and SQL Server.
- SQL Queries: Skill in writing complex SQL queries to retrieve, update, and manage data efficiently.
- Database Design: Understanding of database design principles, normalization, and indexing for optimal performance.
4. NoSQL Databases:
- Document Stores: Familiarity with NoSQL databases like MongoDB, Couchbase, or Firestore.
- Data Modeling: Ability to model data in a non-relational format, taking advantage of flexibility and scalability.
5. API Development:
- RESTful APIs: Mastery in designing and building RESTful APIs that enable communication between the front end and back end.
- Authentication and Authorization: Implementation of secure authentication and authorization mechanisms for API access.
6. Server Management and Deployment:
