As a Twilio Developer Evangelist, Brian Levine shares his experience building his first Twilio project, PhoneDynamo, a phone privacy website that uses a proxy number to forward calls from users' cell phones. He reflects on how easy it was to integrate the web app with the Twilio phone system, thanks to the natural and intuitive API. With his new role at Twilio, Brian aims to empower developers like himself by understanding their pain points and providing guidance on building great things with Twilio. He emphasizes the importance of considering application architecture when integrating Twilio into a larger project, particularly for applications that require high call volumes or need to maintain fast page loads. Brian invites developers to share their Twilio ideas and provides resources and contact information for further assistance.
