❤️❤️❤️ Greetings ❤️❤️❤️ I have reviewed your React Native App Performance Polish project and I can help optimize the existing production app without unnecessary rewrites. I am Ozgur Ozbas, a Full-Stack Mobile Developer with 10+ years of experience in Flutter, React Native, Android, iOS, Firebase, Firestore, REST APIs, and production mobile applications. I can profile the existing app to identify slow startup and navigation points, optimize unnecessary renders and data loading, improve Firebase/Firestore reads and writes, and clean up the Android-specific UI issues. I will also test the final builds on both iOS and Android to make sure the changes don't introduce regressions. My approach would be to measure the current performance first, make targeted improvements, then compare the results so the optimization is based on actual bottlenecks rather than guesswork. Q1. Do you already have specific screens where startup/navigation or Firestore performance is noticeably slow? Q2. Can you provide the current React Native version and Firebase/Firestore structure before I review the codebase? For this focused scope, I estimate **3–5 days**, depending on the existing codebase and the number of affected screens. I can work through Git with clear commits and provide a concise summary of the optimizations made. I can also provide relevant launched-app examples from my portfolio during the discussion. Looking forward to reviewing the app. Best regards, Ozgur Ozbas

@DIGITALJOY

Hi, This is a focused performance/polish pass, and it's the kind of work we enjoy - jumping into a live codebase and tightening it up rather than building from scratch. We've handled React Native apps with Firebase/Firestore backends before, so the usual culprits for slow startup (unoptimized bundle size, heavy JS thread work on mount, unnecessary re-renders) and sluggish Firestore reads (missing indexes, over-fetching, no offline persistence tuning) are familiar territory to profile and fix. Plan: profile startup/navigation first (Flipper/React DevTools) to pinpoint actual bottlenecks rather than guessing, tune Firestore queries/caching for shaky-connection reliability, clean up the Android-only UI inconsistencies, then a full sanity pass on both builds before handoff. Two quick things before I quote a fixed price: Roughly how many screens/views need the Android UI cleanup - a handful or a broader pass across the app? Is the current slow startup more noticeable on cold start (app launch) or navigation between screens (or both equally)? Thanks, Arun

@invoketech

@crtvecode

I see you’re looking to enhance the performance of your React Native app, particularly focusing on trimming startup and loading times, as well as optimizing Firebase interactions. I have extensive experience in refining app performance, especially in ensuring that data reads and writes are efficient, even under less-than-ideal network conditions. For the UI improvements on the Android-only views, I can ensure a more cohesive look that aligns with your overall design principles, which will enhance user experience across both platforms. I’ll also conduct thorough sanity tests on both iOS and Android builds to ensure everything runs smoothly post-optimization. I’m ready to dive into your existing codebase and make these enhancements quickly. Could you clarify if there are specific performance benchmarks you're aiming for with the loading times? Looking forward to your response. Rajavel React Native Developer | Firebase | Performance Optimization

@sharjeelrb

Hello, I can optimize your React Native app by improving startup performance, reducing screen loading times, refining the Android UI, and optimizing Firebase/Firestore for faster and more reliable data synchronization. I’ll also perform end-to-end testing on both iOS and Android to ensure everything runs smoothly after the updates. I have experience working with React Native, Firebase, Firestore, Xcode, Android Studio, and production mobile apps, and I’m available to start immediately.

@slavkom1

Hi! I’ll polish the live React Native app so it feels instantly responsive. Since it’s already on App Store and Google Play, the risky part is touching performance and sync logic without breaking screens. I’ll jump into the existing codebase and focus on: trimming startup and navigation delays, cleaning Android-only UI inconsistencies, and tightening Firebase/Firestore reads and writes for faster, more reliable behavior on shaky connections. I’ll also run a quick iOS + Android sanity build after the changes. I’ve shipped production mobile apps and I’m comfortable with React Native performance work, plus Mobile App Development patterns that keep data stable. Current plan: start immediately after Git access; deliver a quick first pass in 1-2 days, then wrap with testing and release-ready checks the next day. Thanks, Slavko Which specific screens and Firestore queries are currently slow, and do you have target metrics (cold start time, read/write latency) to measure improvement?

@jagratip3

Hi, I can optimize your existing React Native application without disrupting the current architecture, focusing on performance, stability, and a polished user experience across both iOS and Android. I have experience improving production mobile apps by reducing startup time, optimizing Firebase/Firestore queries, fixing platform-specific UI inconsistencies, and ensuring smooth performance on unreliable networks. I will profile the app to identify bottlenecks, optimize navigation and rendering, improve Firestore read/write efficiency with caching where appropriate, and perform full regression testing before delivery. My goal is to deliver clean, maintainable code, a fast turnaround, and a production-ready update with clear documentation and post-delivery support. Best Regards, JP
