Walmart’s top AI engineer behind flagship code agent ‘Code Puppy’ quits — Here’s where he’s headed

One of the top engineers in Walmart’s global tech team, Michael Pfaffenberger, has quit the retail giant after completing a nearly five-year stint. As the creator of Walmart’s internal vibe-coding, AI-powered tool called Code Puppy, the leading executive mapped out the journey ahead and bid farewell to his colleagues in a memo, according to Business Insider.

Pfaffenberger, who climbed multiple ranks over his more than four-year career at Walmart, is leaving the company a year after his flagship AI-driven creation grew from 1,000 users to more than 75,000 and has gained much attention among non-engineers as well.
