Jose de Castro, the new Chief Architect for Twilio Flex, has a long history in building communications platforms, dating back to his fascination with technology and design in the mid-90s. He was drawn to software development as it allows him to build platforms that have a multiplicative effect beyond finished products. His passion for telephony and communications technologies also played a significant role in shaping his career. Jose joined Twilio due to its CEO, Jeff Lawson's, commitment to employees and customers, as well as the company's values aligning with his own. He sees Twilio Flex as an opportunity to disrupt an industry that has remained stagnant for over a decade by providing a programmable model that can be used to create application platforms. This approach is built on cloud-native building blocks that are already adopted by millions of developers, positioning Twilio to dominate the customer engagement market.
