I currently have a mobile app live on both iOS and Android that still struggles with sluggish performance and a few stubborn functionality errors. I need a fresh set of expert eyes to run thorough tests, pinpoint the root causes, and then implement clean, maintainable fixes. Here’s what I’m looking for: • Comprehensive test pass on every core feature, covering both platforms. • Clear, prioritized bug report outlining performance bottlenecks and broken flows. • Well-commented code updates that resolve those issues without introducing regressions. • A new build submitted back to the stores, verified to launch quickly and behave exactly as intended on common device versions. Please be comfortable profiling with Xcode Instruments, Android Studio Profiler, and whichever automated or manual testing tools you rely on every day. If you can turn around a solid, stable release, I’m ready to sign off as soon as performance metrics and critical functions meet spec.
