Dj Walker-Morgan.
Sorry, that was a spoiler, absolutely no tension in the reveal. Anyway, Codepope is Dj and Dj is Codepope.
Dj is a writer, developer and generalised trouble maker who can hoover up technology and ask questions like “Why?” and “Should it be on fire?”.
Over the years he’s worked in many companies, from plucky startups to giant corporations, doing his thing, or an approximation of it.
