Perfect My Cross Platform App

@hirujiyu

➰➰ EXPERIENCED FLUTTER & NODE.JS DEVELOPER SINCE 8+ YEARS Hi there, ✋Based on your requirements, this sounds exactly like the kind of stabilization and optimization work I enjoy most taking an already good product and polishing the final 2% that directly impacts user experience, store approvals, and backend reliability. I can jump into your existing codebase, investigate the root causes properly, and deliver production-ready fixes without disrupting the current architecture. ⭕ Is the mobile app built in Flutter or React Native? ⭕ Are you currently using PM2/Docker/Nginx on the EC2 instance for process management? ⭕ Do you already have baseline performance metrics available, or should I benchmark the current state first? ⚡I’m comfortable working inside existing private GitHub repositories, diagnosing issues quickly, and delivering focused fixes that improve both stability and user experience without unnecessary rewrites. ➰I’d love to review the current setup, pending issues, and deployment flow so I can provide a clear execution timeline and start stabilizing the app immediately. Thank you.

Hello There!!! ★★★★ ( Production-level fixes for iOS permissions, AWS backend stability & app performance optimization ) ★★★★ I carefully reviewed your project and understand you need someone experienced enough to jump directly into an existing live app, resolve the remaining production issues, improve backend reliability and make the whole experiance feel smooth and stable for users across both iOS and Android. ⚜ iOS microphone permission debugging ⚜ Node.js API & MongoDB optimization ⚜ AWS EC2 monitoring and stability fixes ⚜ Play Store permission compliance updates ⚜ Client & server performance profiling ⚜ Memory leak tracing & cleanup ⚜ TestFlight & production-ready deployment support I have strong experiance working with React Native/Flutter apps, AWS infrastructure, MongoDB and App Store troubleshooting. I previously fixed iOS permission dialog issues, backend crashes under traffic spikes and Play Store warning problems for production apps already serving active users. Comfortable with private GitHub repos and debugging existing architectures quickly. My approach would begin with profiling logs, identifying failing permission flows, reviewing API bottlenecks and optimizing requests before testing under load conditions. I can also setup CloudWatch monitoring, alerts and provide proper handoff notes for future maintenance. Would love to discuss the current stack and help you turn the final 2% into a polished and reliable release. Warm Regards, Farhin B.

Hello, I can step into your existing app and resolve the remaining stability, permission, and performance issues needed to bring the product to a polished production level. I will investigate the iOS microphone permission flow, fix the entitlement and permission handling issues across devices, and ensure the voice feature passes TestFlight review reliably. On the backend side, I will profile your Node.js API and AWS setup to identify memory leaks, slow queries, and instability causes while improving monitoring, logging, and scaling behavior for stable uptime under load. I will also resolve the Android permission mismatch causing Play Store warnings and verify the final build aligns with current policy requirements. Both client and server performance will be optimized through API cleanup, request reduction, and runtime profiling to improve responsiveness and startup speed. You will receive tested updates, deployment support, monitoring visibility, and a clear handoff summary with recommendations for future scaling and maintenance.
