Growth Engineer at Credit Karma & Consultant


Hey there,
Which of these articles would you want me to write next? :)

  1. ~10 A/B tests which earn us ~+$10MM/year at Credit Karma (along with conversion numbers)
  2. How to keep shipping A/B tests while reducing technical debt from old dead experiment code
  3. How to involve your analyst/engineering manager/marketing manager in the prioritization, opportunity finding, and sizing which needs to happen before you can build an experiment

Or, what would you like me to write about? Your questions about growth engineering & conversion rate optimization will help me write more–talk to you soon!

Thanks in advance,
David Trejo
