SKILL

• Ariba: On the business side, had more than ten years Ariba consulting and implementation experiences. On the technology side, I just implemented an Ariba 9r2 inspector module to provide a GraphQL interface to pull and update data in both Ariba buyer and Ariba sourcing. The GraphQL query is translated into Ariba Query Language (AQL) automatically. This method greatly increases the flexibility and maintainence ability compared with the SAP Restful API.
