• Act as a trusted advisor for technical and architectural questions related to the Power Platform and its integration with the Lakehouse.
• Promote and enforce best practices for solution design, performance optimization, and lifecycle management within the platform.
• Maintain and continuously improve documentation, including configuration guides, troubleshooting playbooks, and governance guidelines.
• Ensure adherence to data privacy, security, and compliance standards, supporting internal audits and governance reviews when required.

Continuous Improvement:

• Stay current with new capabilities and feature releases in the Microsoft Power Platform and Azure ecosystem.
• Evaluate new functionalities for potential adoption within the Cloud Data & Analytics Platform and prepare proof-of-concepts if needed.
• Identify opportunities for automation and operational efficiency, proposing and implementing improvements in monitoring, deployment, or access management.
