Cloud Elements Orchestration/Workflow

I designed, developed, and documented a web application where you can drag, drop, and connect various cloud elements (like Salesforce, Box, Dropbox, DocuSign, Google Drive, Twilio, and Slack) to build a workflow. For example, you can connect a tile that represents when a manager drops a new file in Dropbox, it sends an email to the user to sign, and once the user signs the document, it then creates a Salesforce record.
