• Architect end-to-end integration flows connecting core enterprise systems, including ERPs (SAP S/4HANA), CRMs (Salesforce), Warehouse Management Systems (WMS), and Retail POS systems.

• Present clear, value-driven architectural proposals to digital leadership, demonstrating how technology choices support business enablement.
• Continuous Improvement & Associate Mentorship (Responsibility)
• Drive a culture of Domain Excellence within the technical team, encouraging developers and junior architects to build deep expertise in specific business segments and processes rather than remaining pure technical generalists.

• Establish a culture of shared learning; mentor junior integration architects and developers, conducting design reviews to elevate collective technical capability.
