## AI overview

An Expedia Group Platform Engineering leader discusses how agentic coding is changing engineering work and what large-scale platforms need to support human and agent users. The article describes shifting human focus toward product thinking, architecture, system design, and context, along with a hackathon experiment intended to encourage exploration of agentic tools.

Expedia Group Technology -- EngineeringWhen your platform's next user isn't humanPhoto by Alex Vasey on Unsplash Earlier this month I hosted a town hall for Expedia Group™ Platform Engineering organization, focused on the rapid progress happening in the agentic coding space, and what it means for us as engineers and as a platform team. Our teams are responsible for the horizontal foundations that power Expedia Group: AI and analytics, data, user experience platforms, edge and API platforms, cloud and infrastructure, as well as EG's developer experience. In other words, we own the "platform of platforms" that thousands of engineers build on every day. Since late last year, with the arrival of models like Opus and modern deep agent harnesses, we've been riding a pretty intense wave of change. Larger context windows and more capable agents have made several things clear. A huge amount of what we call "engineering work" can now be done by agents. The real leverage for humans is shifting toward product thinking, architecture, system design, and context. Our platforms, which were designed for humans, are not yet ready to support agents as a distinct user group. This post is about what it means to run a large-scale platform organization in that world, and how we're retooling our stack, our interfaces, and even our mental models to support both humans and agents at the same time. The change curve for senior engineers For many engineers, especially those who've been in the industry for decades, this isn't just a new toolchain; it's a new inner loop. We're asking people to delegate more of the "typing" to agents, spend more time on what we're building and how it fits into the larger system, and learn how to collaborate with agents as teammates, not just as autocomplete. That would be hard enough in a greenfield startup. In a company that runs a large chunk of the online travel ecosystem, it's even harder. We still must keep the planes in the air: keep sites up, pipelines flowi
