Project description:
"I need an experienced mobile developer to take my existing cross-platform app through one more round of polish and get the updated build live on Google Play and the Apple App Store.

Performance tuning is the top priority. I want noticeably faster launch times and rock-solid stability before the update rolls out. All store assets, screenshots, descriptions, certificates, and privacy policies are already prepared, so you can focus on the code, build, and submission workflow.

Your role will be to:
• Profile the current Android and iOS codebases, pinpoint bottlenecks, and implement fixes that improve speed and reduce crashes or battery drain.
• Resolve the issue that’s blocking me from uploading fresh builds and ensure each store’s requirements—signing, icons, versioning, privacy labels, review notes—are met.
• Compile, sign, and submit release builds, then monitor and respond to any Google Play or App Store review feedback until the update is approved.

Acceptance criteria
• Both stores approve the new version and it appears live.
• Crash-free sessions ≥ 99.5 % in Play Console and App Store Connect.
• Measurable reduction in launch time versus the current production build.

When you reply, link to at least two apps you have personally shipped on both stores and briefly describe the profiling tools you’ll use—Android Studio Profiler, Xcode Instruments, Firebase Performance, or similar.

I’m ready to start as soon as I find the right partner." (client-provided description)
