This talk breaks down how Handoff built and scaled a single Expo codebase across iOS, Android, and Web in production — powering an AI-driven construction product that grew past $1M ARR, starting with one frontend engineer. The goal wasn’t to eliminate platform differences — it was to make them manageable. Shared code gave us speed, but only because we enforced clear boundaries and kept the system simple enough to evolve. Without that, the same approach quickly turns into coupling and slows everything down. Edwin will walk through how the architecture evolved under real product pressure: how they separated shared and platform-specific concerns, how they shipped across all platforms daily with confidence, and how they handled the points where the model starts to stretch. You’ll leave with a practical, experience-backed approach to using Universal Expo as a lever for speed — and scaling it without losing control.
