• Design and develop RESTful APIs using Python and Fast API for Data Access (Async, Online, and Pipeline APIs)
• Implement asynchronous batch extraction APIs with job submission, status tracking, and result retrieval
• Develop synchronous APIs for targeted data lookups and metadata queries
• Integrate APIs with Enterprise API Gateway and Sentinel authentication and authorization mechanisms
• Implement API-level security, rate limiting, and access controls in compliance with HIPAA requirements
• Integrate ECG transport for secure batch data delivery to external consumers
• Collaborate with Data Engineers to wire APIs with Snowflake- and S3-based extraction logic
• Build and maintain Skills Registry and supporting platform services
• Support SDK development and API client wrappers for internal developer consumption
• Ensure comprehensive audit logging of all API requests and responses to Data Operations Metadata (DOM)
