Client: Cisco

• iFlow Configuration: Configured and deployed standard, point-to-point Integration Flows (iFlows) to connect SAP ERP with cloud-based applications.
• Adapter Management: Set up and tested basic cloud connectivity utilizing standard adapters such as HTTPS, SOAP, SFTP, and Mail.
• Data Mapping: Created graphical data maps to transform data payloads between common enterprise formats, including XML to JSON and CSV structures.
• System Monitoring: Monitored the Message Processing Logs (MPL) daily to identify, track, and resolve failed or stuck integration messages.
• Basic Troubleshooting: Analyzed runtime message errors by turning on trace levels and checking the CPI dashboard to ensure smooth interface operations.
• Documentation: Maintained technical design documentation, mapping sheets, and unit test cases for all developed interfaces.
• Advanced iFlow Design: Engineered complex, asynchronous, and fault-tolerant iFlows using advanced Enterprise Integration Patterns (EIP) like Splitters, Gatherers, Content-Based Routers, and Multicast.
• High-Volume Messaging: Implemented JMS Queues and data store persistence mechanisms to handle high-volume transaction peaks, ensuring zero data loss.
• Custom Scripting: Authored reusable Groovy Scripts and JavaScript inside CPI steps to handle dynamic header manipulations, payload parsing, and advanced routing conditions.
• Hybrid Connectivity: Deployed and managed the SAP Cloud Connector to establish highly secure communication channels between on-premise networks and the SAP BTP cloud environment.
• Security Implementation: Configured robust end-to-end security measures including OAuth 2.0, PGP Encryption/Decryption, and X.509 Certificate-based authentication.
• Exception Handling: Designed and built centralized, automated exception handling subprocesses within iFlows to trigger alerts via email or external ticketing systems (like ServiceNow) upon failure.
• Transport Management: Managed the end-to-end transport lifecycle of integration packages from Development to Quality and Production environments using SAP Cloud TMS.
