Scaling Uber: Thuan Pham on Engineering and AI
This episode of The Pragmatic Engineer features Thuan Pham, Uber’s first and longest-serving CTO and current CTO of Faire. The interview reviews Pham’s seven-year tenure at Uber — stabilizing a fragile system, re-architecting a monolith into microservices, and scaling the engineering organization — and covers the platform-and-program organizational split, the Helix mobile app rewrite, rapid launches such as Uber China, and the internal tools and observability systems that supported growth. Pham also describes dividing his time into three “tours of duty,” current work at Faire including AI uses like “swarm coding,” and career advice. The newsletter lists 14 key takeaways summarizing lessons on hiring, naming conventions, global hiring, architecture rewrites, and AI’s role in software engineering.
Practical engineering and organizational lessons about scaling platforms, microservices, observability, and AI are informative for technical teams, but the episode is an interview/podcast without direct, immediate industry-wide implications for AdTech.

Building AI-native Engineering Teams — Anthropic's Fiona Fung
Fiona Fung, Head of Engineering for Claude Code and Cowork at Anthropic, describes how AI is reshaping engineering organization, workflows and productivity. Drawing on 25+ years of engineering experience including 11 years at Microsoft (Visual Studio, TypeScript) and product leadership at Meta (including founding Facebook Marketplace and work on AR glasses and Instagram infrastructure), Fung discusses running teams that now ship substantially more code, which roles AI will transform, specific ways her teams use Claude and Cowork, and managerial changes driven by Claude “routines.” The piece highlights operational gains (Anthropic engineers reportedly ship ~8x more code per quarter versus 2021–2025) and surfaces unresolved challenges such as context-switching and the broader unsolved problems in AI.
Uber Engineers Create AI Chatbot of CEO for Productivity
Uber CEO Dara Khosrowshahi said in an interview on Steven Bartlett’s podcast that Uber engineers have built an internal chatbot — referred to internally as a “Dara AI” — which teams use to rehearse and tune presentations before meeting senior leadership. Khosrowshahi said roughly 90% of Uber’s software engineers use AI tools in their work and about 30% are “power users” who are rethinking the company’s software architecture. The detail was reported by Business Insider and published by TechCrunch on February 24, 2026. Khosrowshahi described the tools as substantially increasing engineering productivity.
Uber CPO on Hotels, AV Labs, and Data Strategy
Uber’s chief product officer Sachin Kansal describes the company’s expansion beyond ride-hailing and delivery into hotel bookings (via Expedia), boat rentals, “shop for me” features, and financial-services experiments for drivers. Uber has a six-month-old business unit called AV Labs that deploys sensor-equipped vehicles to gather driving data to support autonomy partners and build a data layer. Uber is also commercializing data-labeling work using its earner base and has commercial relationships with generative-AI companies for labeled data (with safeguards against recording in-ride conversations). Uber One has 51 million members and drives substantial bookings; Uber says Eats has recently been profitable. Kansal emphasizes selective partnerships and integration depth, while noting competition from companies including Waymo (also a partner/competitor), Lyft, Didi, DoorDash and others.
