Showcase Your Expo Skills with a GitHub README Badge

Use this markdown in your README:

![Expo](https://img.shields.io/badge/Expo-000020?style=for-the-badge&logo=expo&logoColor=white)

The #000020 is Expo's very dark navy-black — a near-black that reflects Expo's minimalist, dark branding. The expo logo identifier renders Expo's circle logo from Simple Icons. This dark badge pairs naturally with React Native, TypeScript, and other mobile development badges in a cross-platform developer profile.

Expo has two primary development modes — distinguish between them in your profile or project descriptions:

• Expo Go (Managed workflow): Maximum convenience for prototyping, limited to Expo SDK APIs, instant preview on device
• Development builds: Custom native modules, full React Native capabilities while keeping Expo tooling
• EAS Build: Cloud building for iOS and Android without local native toolchains
• EAS Update: Over-the-air JavaScript bundle updates without App Store review cycles
• EAS Submit: Automated App Store and Play Store submission
• Expo Router: File-based navigation system for React Native (similar to Next.js for mobile)

Mentioning EAS (Expo Application Services) experience signals that you ship production applications through the full Expo workflow, not just prototype in Expo Go.

Expo sits within the React Native ecosystem:

• React Native stack: Expo + React Native + TypeScript + React Navigation
• Modern Expo stack: Expo + Expo Router + TypeScript + NativeWind (Tailwind for RN)
• Backend connected: Expo + React Native + Supabase/Firebase + TypeScript
• Full-stack mobile: Expo + tRPC + Next.js + PostgreSQL (monorepo pattern)

Expo and bare React Native represent a spectrum of control vs. convenience. Listing both Expo and React Native in your profile (with context about which projects used which) shows you understand when the managed Expo workflow is appropriate and when ejecting to bare React Native workflow is necessary for custom native modules.

Expo applications are JavaScript or TypeScript — your language stats will accurately reflect whichever you use. TypeScript Expo projects show as TypeScript, which is the modern standard for production Expo apps.

For pinned repositories, an Expo project with a clear README including screenshots (rendered inline by GitHub), installation instructions (both Expo Go QR code and EAS build instructions), and documented architecture decisions is a strong mobile portfolio piece. Adding a link to the published app on the App Store or Play Store transforms your GitHub repository from a code showcase into a shipped product portfolio, which is substantially more compelling to hiring managers.
