• Migration Strategy: Design conversion paths, phased rollouts, and coexistence frameworks between legacy SAP ECC and S/4HANA.
• Integration Topology: Architect resilient, scalable, and real-time integration flows (iFlows) utilizing SAP CPI / Integration Suite.

Technical Execution & Governance

• Debt Remediation: Evaluate legacy custom code within SAP ECC and formulate strategy plans to decouple or remediate it.

• Aerospace Regulations: Ensure all designed solutions strictly adhere to AS9100 quality standards, ITAR, and global export control laws.
• Asset Tracking: Design system logic to manage high-consequence data, including engine part serialization and life-limited component tracking.

Best Practices & Innovation

• Clean Core Enforcement: Champion standard-first governance, utilizing SAP BTP for application extensions to eliminate core modifications.
• Delivery Frameworks: Infuse modern DevOps pipelines, Agile frameworks, and SAP Activate methodologies into the project lifecycle.

Stakeholder Management & Leadership

• Trusted Advisory: Serve as a technical bridge, translating complex architectural choices into clear business value for executives.
• Cross-Team Collaboration: Lead, mentor, and align global delivery teams, functional analysts, and development partners toward a unified vision.

• Aerospace Modules: Exposure to relevant modules/solutions (e.g., SAP PLM, Production Planning, Quality Management, or MRO).
• Modern Protocols: Advanced proficiency with OData APIs, RESTful web services, and Cloud Connector.
• Methodologies: Solid grasp of SAP Activate, Agile frameworks, and cloud-native DevOps pipelines.

Preferred Qualifications
