Experience

Massachusetts Medical Society | MuleSoft Integration

This project was to integrate legacy systems of MMS with front-end technologies using the MuleSoft platform. Different back-end systems—like Janrain, Catalyst, and NEJM—were integrated with the Anypoint platform using Mule 4, Design Center, and Runtime Studio. Documentation and API design was done using Design Center, and we used Anypoint Studio for implementation. Transformations used DataWeave 2.0. and multiple connectors—including HTTP, Database, and Amazon S3—were utilized in integrations. For the unit testing of flows, MUnit was implemented.
