The winner of the Salesforce developer contest was Michael Norton's Twilio Messaging for Salesforce app, which enables users to send voice or SMS messages to Leads and Contacts and track them as Activity records in Salesforce. The app allows users to type in phone numbers and messages on a custom Visualforce page, which then sends the message via SMS or voice depending on user selection. The developer, Mike Norton, is a Salesforce Certified Advanced Developer and Twilio Advocate at AAA of Northern California, with his blog featuring information on developing with the Salesforce API. The company encourages developers to participate in its monthly Twilio-powered contests, providing resources and support for building innovative solutions using Twilio's cloud communication platform.
