"Kaoru is one of the big reasons why I love work so much...I feel like he does way more than what's asked of him, and he has a drive towards having good engineering practices being applied at work."
Justin Lee - Software Engineer @ Sift Science

"Hmm. Yeah this is a complicated one to debug. I would see if you can [reproduce] with your own user. If you can then ping Kaoru. He likely has his hands full, but he knows his s**t"
