Scaling Enterprise CI/CD: A Migration Success Story

Presentation byMichael Blanchard

From legacy CI/CD infrastructure to lightning-fast Expo EAS: discover how we transformed our enterprise React Native build system while dramatically reducing both build times and infrastructure costs. This talk walks through our journey integrating Expo EAS with GitHub Actions, and creating a modern native app workflow that scales with development needs. You'll leave with practical strategies for migrating complex build systems, optimizing CI/CD performance, and measuring the real impact on developer productivity.

Brownfield React Native at Scale: Ship Dozens of Micro-Apps Daily

Toss, South Korea’s leading fintech app, runs 40+ micro React Native apps inside a brownfield super-app with 20+ daily deployments. We’ll share how we customized the bundling pipeline—replacing Metro with esbuild and enabling dynamic multi-bundle loading—to achieve sub-10s builds, sub-200KB bundles, and scalable React Native deployments at scale.

React Native in 2026: Not Your Daddy’s React Native

React Native has changed a bunch, and if you haven't looked at it lately you're in for some fun. We'll walk through building a real app with (my beloved 😍) Expo. Talk about project setup to app store submission with detours into AI-assisted development and ofc, talk about the casual masochism that is mobile dev.
