Join us for the Callstack x Expo AI Meetup in San Francisco, an in-person, developer-first event focused on AI-native mobile development.

This meetup is built for engineers who want to understand how coding agents are changing real mobile workflows. We’ll look at how React Native and Expo apps are being built, reviewed, tested, and shipped when agents become part of the engineering process, not just a side tool.

Expect practical talks from Expo, Callstack, and mobile teams using agents in production workflows at Expensify. We’ll cover AI-native mobile development, autonomous QA on every pull request, and production lessons from teams using agents across development, CI, QA, and release pipelines

Talks and speakers

Autonomous Mobile QA for Expo Apps with Cloud Agents

Code review for mobile apps does not scale well when teams start shipping with AI agents. This talk covers a cloud agent that runs apps on real devices, explores user flows autonomously, and attaches screenshots, recordings, and logs directly to pull requests.

The setup works with the CI teams already use, including EAS Workflows, so you do not need extra infrastructure before getting started. The goal is to make mobile QA visible inside the pull request, where engineering teams already make decisions.

Building a native app with Expo Agent

Expo Agent is Expo’s take on agentic mobile development: describe the app you want and get a production-quality iOS and Android app on the other side.

Evan Bacon will show what the Expo team has been building, how the workflow behaves in practice, and what is happening under the hood. Expect a hands-on look at Expo Agent and a chance to ask questions about how it fits into the Expo ecosystem.

Important RSVP update

We have a waitlist with people hoping to join. If you are no longer able to attend, please update your RSVP to “Not Going” as soon as possible so someone from the waitlist can take your spot.

Food will be provided, and it’s going to be a strong evening of technical talks and conversations with the React Native, Expo, and AI-native mobile development community in San Francisco.
