I focus on thorough, hands-on testing to ensure flows like signup, purchases, restores, and core navigation behave reliably before launch. Let's get in touch Thanks

@larasatik4

Hi, I’ve read your scope for a Technical Review, API validation and RevenueCat testing on iOS and Android and I’m confident I can deliver a clear, actionable assessment. I’m a mobile engineer with Flutter/React Native experience and multiple apps published on Google Play. I focus on polished UI, stable production builds and fast, iterative testing cycles. My approach: review app configuration and staging/production switches, verify environment variables and APIs on real devices, validate RevenueCat production keys, entitlements and restore/purchase flows, and test OAuth and native permissions. I’ll produce a concise summary of findings, prioritized issues and remediation steps. Next step: I can start with a short sync to access test builds and keys, then run device tests and deliver the report. Do you already have RevenueCat production keys and access to test builds on real devices (or device farm credentials), or should I use sandbox/test accounts you provide? Thanks, Larasati
