• Configured and managed SAP API Management (APIM) artifacts — API proxies, policies, and access control — to expose and secure integration endpoints for external consumption.
• Performed tenant-to-tenant artifact migration and packaging, including isolating and reconstructing individual Value Mapping artifacts from package exports for cross-tenant import.
• Provided L2/L3 production support and hyper-care for critical integration flows, driving root-cause analysis and resolution for deployment and runtime failures (e.g., processor/version mismatches in XSLT mapping steps).
• Authored technical design documentation and mentored junior integration developers on CPI best practices, debugging methodology, and delivery standards(EAI/SOA).
• Recognized with the Star of the Month Award (2x), On The Spot Award, and Special Initiative Award for consistent delivery excellence and proactive problem-solving.
