Boron/Peso
As part of the 2018-2019 refactoring effort at Evernote, I led the teams responsible for two major projects: redesigning the desktop applications into a common user experience across clients (Project Boron), and a reimagining of the editor experience built on ProseMirror (Project Peso).
These efforts each posed significant challenges, as the desktop experiences on Mac and Windows had always been fragmented (in some cases features were implemented differently, or unique to one client or the other) and the switch in underlying technology for the editor meant fundamentally changing the user experience of some common behaviors. In essence, we were forced into a top-to-bottom redesign that needed to drive users into willingly adopting significant change while still protecting the workflow idiosyncrasies of tens of millions of active users.
