Have you had experience releasing applications into production environment?

Yes, experience in releasing applications to production typically involves several stages:

• Preparing the release build (for example, using Xcode for iOS or Gradle for Android).
• Testing and quality assurance.
• Configuring certificates and profiles (for iOS).
• Uploading the application to app stores (App Store, Google Play) through the respective portals.
• Post-release monitoring, collecting feedback, and fixing bugs.

Such experience is important for understanding the process of delivering the product to users and managing versions.
