In this episode, we talk to Brendan Keeler, head of product at Flexpa, also known as Health API Guy. He talks about the beginnings of his career at Epic, getting “sucked into the black hole” of interoperability and interfacing, and the subtleties of building a product development team, which he did at Zus Health and Redox. He also weighs in on the Trusted Exchange Framework and Common Agreement (TEFCA), Amazon’s purchase of One Medical, and more. Find him on Twitter at @healthbjk.
