This is so impressive. Reminds me of when I (a copywriter) would sit next to a great designer, saying "try this" and "what about that" and watching my nebulous feelings about the thing turn into reality.
That's one of the things I really missed while working at a big co like Airbnb. The infra team sat separately (depending on the re-org, in a different building) from the design team. I feel like so much great stuff happens when sitting side-by-side.
