As Lead API Integration Support, my role is to help users who want to integrate with Jubelio can use our API well. Helping here includes preparing API documentation that is easy to understand, preparing Flowcharts or Sequence Diagrams according to different user needs depending on the business being run and finally developing new APIs or changing existing APIs to accommodate User needs.Helping the Sales team is also one of the things I do, here I help explain to prospective Clients or Partners why they have to integrate via API, the benefits they get, and also the solutions that can be achieved.In addition, I also manage the team to prepare and divide the appropriate tasks so that each task can be done optimally in terms of time or complexity.
