Thuan Pham joined Uber as its first CTO when the company had 40 engineers and 30,000 rides per day, with systems crashing multiple times a week. Over seven years, he stabilized the platform, led the monolith-to-microservices migration, and built the engineering organization that scaled to handle global demand. He is now CTO at Faire, a B2B wholesale platform.
The episode covers three distinct phases Pham calls 'tours of duty': stabilization, re-architecture, and org scaling. The most technically dense sections cover the platform-and-program split, the Helix app rewrite, and how Uber launched in China in five months against an original 18-month estimate. The reasoning behind each of those decisions is where the real value is, not just the outcomes.
Pham also addresses how Faire is deploying AI today and what he thinks it means for software engineering roles going forward. The full conversation is available on YouTube, Spotify, and Apple Podcasts, with a timestamped transcript linked at the source.
