Firebase Download Setup for EAS

I have an Expo EAS project that already builds successfully, but I still need a clean way for testers to download the latest packages. The immediate task is to configure my existing Firebase project so a downloadable Android APK is always available and—where possible—the same flow works for the iOS build as well.

You will work directly inside my Firebase console (or guide me step-by-step if you prefer) to:
• Create or adjust the storage path, security rules, and any required cloud function so each new build is uploaded automatically and served through a short, shareable link.
• Make sure the download link works on both Android and iOS devices; Android must deliver the APK, while iOS can point testers to the .ipa or TestFlight link.
• Provide a concise hand-off note explaining how I can repeat the process for future releases.

I can give you access to the repo, current EAS workflow file, and the Firebase project as soon as we get started. If you have set up a similar pipeline before, a quick message outlining that experience will help me pick you faster.
