• Collaborate with product managers, solution architects, and other developers to define API requirements, specifications, and data models.
• Ensure APIs adhere to industry best practices, architectural standards, and security protocols (e.g., OAuth, JWT, API Gateway policies).
• Write clean, well-documented, and efficient code following coding standards and best practices.

• Testing & Quality Assurance:

• Develop and implement comprehensive unit, integration, and end-to-end tests for APIs to ensure reliability, functionality, and performance.
• Perform API load testing, stress testing, and security testing to identify and address bottlenecks or vulnerabilities.
• Collaborate with QA engineers to ensure thorough testing and defect resolution.

• Integration & Documentation:

• Facilitate seamless integration of APIs with various front-end applications, third-party services, and internal systems.

• Provide support and guidance to consumers of the APIs, assisting with integration challenges and clarifications.

• Maintenance & Support:

• Monitor API performance, availability, and error rates, implementing necessary optimizations and fixes.
• Troubleshoot and debug production issues related to APIs, providing timely resolutions.
• Participate in code reviews to ensure code quality, adherence to standards, and knowledge sharing within the team.
• Manage API versioning and deprecation strategies.

• Collaboration & Innovation:

• Work closely with cross-functional teams, including front-end developers, DevOps, QA, and product teams.
• Actively participate in agile ceremonies (sprint planning, daily stand-ups, retrospectives).
• Stay updated with the latest API trends, technologies, and security best practices, proposing innovative solutions.
• Contribute to architectural discussions and technology stack decisions related to APIs.
