• Maintain functional and API contract parity with existing services.
• Work with existing shared libraries/SDKs and FastAPI frameworks.
• Integrate APIs with backend systems and data stores.
• Implement request validation, error handling, authentication/entitlement logic, and API transformations.
• Develop unit and integration tests for migrated services.
• Perform API contract and functional validation against existing services.
• Troubleshoot application, integration, and performance issues.
• Participate in code reviews, technical discussions, and design reviews.
• Prepare API/OpenAPI documentation and operational handover documentation.
• Follow established coding, CI/CD, security, and development standards.
