My Kotlin-based Android app is feature-complete; I’m now down to the last mile—verifying the monthly subscription flow (Google Pay / Play Billing) and getting the release live on Google Play. Here’s what I need from you: • Payment flow validation – Run end-to-end tests on the existing Google Pay integration and confirm that a monthly subscription can be purchased, renewed, and cancelled without issues. – Identify any Play Console configuration gaps (products, pricing, license testing) and walk me through fixes. • Automated test setup – Add or refine basic automated tests that cover the critical billing paths so I can rerun them before future releases. JUnit, Espresso, or your preferred framework—whatever speeds this along with minimal code changes. • Store launch assistance – Complete closed/internal testing in Play Console, resolve compliance checks, and push the production build. My personal verification is already approved, so it’s just the release steps. Code edits should be limited to what’s strictly required for testing hooks or Play Billing settings; the core app logic is otherwise locked. You’ll be a perfect fit if you’ve shipped Kotlin apps with in-app subscriptions and know the nuances of the Play Billing Library, Google Pay, and the Play Console release process. Deliverables: APK/AAB ready for production, passing automated test suite, and a live listing visible in the Play Store.
