If you're building React Native apps with Expo and still hitting random build failures, you're probably making one of these mistakes. I've seen every single one of them working with dozens of developers.

1. Not using build profiles correctly

Most devs have a single build config and wonder why their dev builds take 15 minutes. You need three profiles minimum:

{
  "build": {
    "development": {
      "developmentClient": true,
      "distribution": "internal"
    },
    "preview": {
      "distribution": "internal"
    },
    "production": {}
  }
}

Dev builds use developmentClient: true so you get fast refresh. Preview builds are for TestFlight/internal testing. Production is production. Stop mixing them.

2. Ignoring credential management

Every few weeks someone DMs me: "My build failed and I don't know why." Nine times out of ten, their provisioning profile expired or they're using the wrong distribution certificate.

Run eas credentials regularly. Let EAS manage your credentials unless you have a specific reason not to. And never share credentials across teams without a proper setup.

3. Pushing full rebuilds when an OTA update would do

Changed some text? Fixed a style? Updated an API endpoint? You do not need a new binary build for that.

eas update --branch production --message "Fix: updated API base URL"

OTA updates deploy in seconds. Binary builds take 10-20 minutes. Know when to use which.

4. No CI/CD pipeline

If you're still running eas build from your laptop, you're one spilled coffee away from a deployment disaster. Set up GitHub Actions:

• Push to main → OTA update to production

• Push to staging → Preview build + OTA update to staging channel

• Tag a release → Full production build + submit to stores

This takes 30 minutes to set up and saves you hundreds of hours.

5. Not testing OTA updates with channels

Shipping an OTA update straight to production without testing it on a staging channel first is reckless. Use channels to manage environments:

eas channel:create staging
eas update --branch staging --message "Test: new onboarding flow"

Test on staging. Verify. Then promote to production. This is non-negotiable for professional apps.

You're in. Let's ship production apps together.

Welcome to Expo EAS & OTA Mastery — you've just joined a focused mentorship built for developers who are done fumbling with builds and ready to deploy like professionals.

Here's how to get started:

1. Start the course — Work through the 5 modules in order. Each lesson builds on the last, from EAS fundamentals through CI/CD pipelines. Don't skip ahead.

1. Join the Community Chat — Ask questions, share wins, post your eas.json configs for review. I'm active here daily.

1. Check Updates & Announcements — That's where I post new lessons, bonus content, and important changes to EAS/Expo tooling.

What you'll be able to do after this course:

• Configure and run EAS Build for dev, preview, and production profiles

• Manage credentials and signing without losing your mind

• Push OTA updates with channels, rollbacks, and multi-environment setups

• Set up CI/CD with GitHub Actions that auto-builds and auto-deploys

• Debug failed builds and recover from production incidents

Ground rules:

• Do the exercises. Reading code isn't the same as writing it.

• Ask specific questions. "It doesn't work" isn't a question. Share your error, your config, and what you've tried.

• Ship something real. The final project is designed to go into your portfolio.

Let's get to work. 💪
