We just released Sonar, an extensible mobile app debugger. In this Episode Pascal interviews Emil who started the project 18 months ago about what inspired him to build it and how Sonar is used across Facebook today.

This month Emil and Pascal talked to Will Bailey. Will has a long history at Facebook building tactile experiences and open source libraries. Now Will works at Instagram. Apart from hearing about Will's history at Facebook, we focused on the intersection of design and software engineering, something all of us are very passionate about.

In this episode we interview Mihaela who works on the Native UI Frameworks team. We talk about Litho and Sections and how open source at Facebook works.
