Salesforce Marketing Cloud REST API Integration

An insurance tracking website for customers to submit active insurance policies. As a back-end developer, I authored a .NET Core/REST API solution to encapsulate and simplify functionality from the Salesforce Marketing Cloud (SFMC). The core functionality was to deliver email via SFMC content management, populate a messaging queue, process the message queue by running various insurance matching algorithms, and, finally, trigger a secondary email based on these results.
