Design database schemas, optimize queries, and implement data models to ensure efficient and reliable data storage and retrieval. Perform database migrations, backups, and recovery procedures as necessary.
Code Optimization and Performance:

Write clean, maintainable, and efficient code following best practices and coding standards. Identify and resolve performance bottlenecks, memory leaks, and other issues impacting application performance. Use profiling and monitoring tools to analyze and optimize application performance and resource usage.
Testing and Quality Assurance:

Write unit tests, integration tests, and end-to-end tests to ensure the reliability and stability of the application. Conduct code reviews and participate in peer programming sessions to maintain code quality and share knowledge. Collaborate with quality assurance teams to identify and resolve software defects and improve test coverage.
Documentation and Collaboration:

Document technical specifications, API endpoints, and architectural decisions to ensure maintainability and knowledge sharing. Collaborate effectively with cross-functional teams, including front-end developers, product managers, and system administrators, to understand requirements, provide technical insights, and deliver solutions.
