Thuan Pham joined Uber as its first CTO when the company had 40 engineers and 30,000 rides per day, with the system crashing multiple times a week. Over seven years, he rebuilt it: monolith to microservices, fragile to global scale. He is now CTO at Faire, a B2B wholesale platform, and this conversation covers the full arc of that infrastructure transformation.
The episode goes beyond the headline numbers. Pham breaks down his time at Uber into three distinct tours of duty, stabilization, re-architecture, and org scaling, and explains the platform-and-program split that became a structural template for large engineering orgs. The detail on launching Uber in China in five months against an 18-month estimate is worth the full listen alone.
The second half covers what Pham is doing at Faire with AI, and how he thinks AI is changing the practice of software engineering. If you want the mechanics behind how a system survives hypergrowth, not the mythology, this is the primary source.
