The only thing I know her from is I/O, where she kicks off/MCs the dev keynotes. Her I/O bio says "VP and GM of Developer X" and "Head of Developer Relations", but I have no idea if "Developer X" is developer experience, or a reference to the old X skunkworks, or something else entirely.

EDIT: Dug a little more and it's the group formerly known as Developer Product. So Firebase, etc. makes sense. Successor to Jason Titus.
