During June 2025, Karmatys focused on enhancing iOS build reliability within the expo/eas-build repository by developing Pod Install Deployment Mode. This feature introduced an opt-in environment variable that enables the --deployment flag for CocoaPods pod install, allowing teams to enforce stricter pod installation constraints without custom scripts. By improving error messaging during the pod install phase, Karmatys reduced troubleshooting time and made diagnostics more efficient. The work leveraged TypeScript and build tools expertise, with an emphasis on CI/CD workflows. These changes laid the foundation for broader adoption, aiming to increase consistency and reduce build failures across iOS projects.
