Our live emergency & personal-safety app is throwing errors on both Android and iOS. I need an experienced React Native developer who can jump straight into the existing codebase, trace the root causes, and apply solid fixes without introducing regressions. The very first obstacle is the SOS / emergency notification flow: push alerts are simply not sending. Once that is stable, I want you to work through the remaining crashes, deep-link quirks, location / background-service hiccups, and any Firebase FCM or APNs issues you uncover. You will be cloning a mature GitHub repo, stepping through the code in a real-device debugging setup, and submitting clean, well-documented pull requests. I expect meaningful commit messages, reproducible steps for every bug you squash, and confirmation that the fix works on at least one recent Android and one recent iOS handset. Acceptance criteria • SOS push notifications reliably reach all intended recipients in real time • No new crashes reported in Crashlytics for the components you touch • Location tracking and permission prompts operate as intended in foreground and background • Deep links open the correct screens consistently on both platforms Let me know about projects where you have wrangled similar React Native / Firebase stacks, your availability this week, and your hourly rate so we can get started right away.

Hi, This is exactly the kind of React Native work I’m comfortable with: taking an existing production app, tracing the real root cause, and fixing it without introducing regressions. I’ve worked extensively with React Native across iOS and Android, including push notifications, real-time functionality, backend APIs, permissions, and production release pipelines. A highly relevant example is **reSTASH**, a React Native iOS/Android marketplace with 1,500+ users and 600+ listings. I handled the mobile/backend implementation, including push notifications, real-time bidding, messaging, APIs, and releases. I’ve also worked on **FoodSwitch**, a React Native app with 400k+ downloads across 17 markets, giving me experience debugging and maintaining mature production mobile applications. For your SOS issue, I’d trace the complete notification chain: FCM/APNs configuration, device tokens, permissions, backend delivery, foreground/background behavior, payload handling, and deep-link navigation. Then I can systematically tackle the crashes, location/background issues, and platform-specific quirks. I’ll provide reproducible steps, meaningful commits, clean PRs, and real-device verification on both platforms. I’m available now and can start this week. **$20/hr**. If you provide the repository and current Firebase/iOS configuration, I can start with the SOS flow immediately.

Hi — Elias here from Miami. I see that your emergency and personal safety app is facing issues on both Android and iOS platforms. This is crucial, as reliability and user trust are paramount in such applications. What usually matters most here is understanding the root cause of the errors. A common issue in systems like this is often related to state management or compatibility between libraries. The tricky part is usually ensuring that the app performs seamlessly across different devices while also handling real-time data effectively. To address these challenges, my approach would involve a thorough debugging process, focusing on isolating the errors and stabilizing the app. I would structure the code to enhance maintainability and ensure that future updates are straightforward. I’ve worked on similar mobile applications where I implemented robust error handling and optimized performance, which significantly improved user experience. A few questions to better understand the scope: Q1 – What specific errors are you encountering on both platforms? Q2 – Are there any particular features that are critical for the app's functionality? Q3 – How do you envision the app scaling in the future? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hi, SOS push alerts not firing usually traces back to FCM token registration breaking on app resume or a silent APNs cert/entitlement mismatch on iOS. I'd clone the repo, get it running on a real Android and iOS device first, then instrument the notification handler to see exactly where the payload dies before touching anything else. After that I'd move to the background location and deep-link issues, since those often share the same root cause (stale permissions state after OS updates). I'll submit PRs per bug with reproducible steps, not one giant patch. We're a JS/RN focused team and have handled similar FCM/APNs breakages on live apps before. Given the acceptance criteria here, the $15-25 range feels tight for the debugging depth involved, happy to discuss scope or a small paid trial fix on the SOS flow first so you can see the work before committing further.

Hello, ✅ Your priority is clear: stabilize the live React Native safety app fast—starting with the SOS/emergency notification flow—without causing regressions across Android and iOS. We’re a JS-focused team with 8+ years across React, Vue, Next, Node, and mobile troubleshooting. Shipped 80+ React/Next/Vue apps — dashboards, SaaS UIs, e-commerce frontends. Top Rated on Freelancer with long-term JS engagements. For this React Native/Firebase stack, we’d jump into the existing GitHub repo, reproduce issues on real devices, trace root causes around FCM/APNs, deep links, background location/services, and submit clean PRs with meaningful commits, repro steps, and verification on recent Android + iOS handsets. We also watch Crashlytics closely so fixes stay stable. Two quick questions: 1) Is the SOS flow using Firebase Cloud Messaging only, or is there any server-side trigger/auth layer involved before APNs/FCM dispatch? 2) For state/auth/navigation, are you using Redux/Context + React Navigation, and are the deep-link issues tied to cold start, background resume, or logged-out users? I’m available to start this week and can align quickly on hourly engagement once I review the repo/error patterns. Drop me a message — happy to align on stack. **Please let me know your thoughts. Looking forward, Roman**

Hello!, I am a Florida-based senior software engineer(frontend, backend, ecommerce, etc) with 15+ years of experience, and I read your React Native safety app post carefully. I understand the main issue is that a live emergency and personal-safety app is now throwing errors on both Android and iOS, so this needs quick, precise debugging, not guesswork. I’ve worked extensively with React Native, TypeScript, Android, iOS, and production app troubleshooting, and I’m very comfortable stepping into an existing codebase, finding the real root cause, and fixing it cleanly without creating new problems. My approach would be: 1) reproduce the issue on both platforms 2) inspect logs, build output, and recent changes 3) isolate the failing module, dependency, or native bridge issue 4) patch, test on Android and iOS, and share a clear summary of the fix I’m the kind of developer who pays attention to detail because for a safety app, reliability matters. I’d rather identify the exact cause once than apply a temporary workaround. Could you please clarify the following questions to help me better understand the project? 1) What exact error messages are you seeing on Android and iOS? 2) Did this start after a recent update, dependency change, or code push? 3) Can you share repo access, build logs, or the failing screens so I can move straight into root-cause analysis? If helpful, I can jump in quickly, diagnose the issue, and get you a practical fix with minimal back and forth. - James

Hi, I’ve worked with React Native apps using Firebase to handle push, deep links, and background tasks, and I know what it takes to get alerts to land reliably on both Android and iOS. I’d start by reproducing the SOS flow on a recent device, add targeted log points, and isolate unstable paths before fixing with clean, well-documented patches. One technical risk is platform-specific push behavior with FCM/APNs and background execution limits, which can surface only under real usage. What Android/iOS devices and OS versions should we validate the SOS flow on first? What should happen if a deep link fails to open, retry policy and user messaging? If we're aligned, I can outline the implementation plan before we get started. Best regards, Brandon

The first thing I’d trace is the SOS notification path end-to-end: token registration, Firebase/FCM delivery, APNs configuration, backend trigger, and the recipient targeting logic. Once that is reproducible, I’d work through the related React Native issues around background location, permissions, and deep links using real Android and iOS devices, keeping each fix isolated in a PR to avoid regressions. For the SOS flow, are notifications triggered directly from the app or through a backend service?

The SOS failure should be traced through the entire notification path first: device token registration, Firebase/APNs configuration, backend delivery, and foreground/background handling. In a mature React Native app, I’d reproduce the failure on real Android and iOS devices, verify the FCM/APNs payload and delivery logs, then work through the location, background-service, and deep-link issues without disturbing working flows. I’d keep each fix isolated in a PR with reproducible steps and Crashlytics checks, so regressions are easy to catch. Is the SOS notification triggered directly through FCM from your backend, or does it pass through another notification service first?

Hello, Your immediate priority is getting the SOS/emergency notification flow reliable again, and I understand that this requires more than simply patching the visible error. I’ve worked with React Native applications involving Firebase, push notifications, location services, background processes, and API-driven workflows, so I can step into the existing codebase, trace the root causes, and fix the issues without disrupting working functionality. I can start by reproducing the FCM/APNs notification problem on real Android and iOS devices, then work through the remaining crashes, deep-linking, location/background-service issues, and platform-specific problems. I’ll keep the fixes focused and maintainable, with meaningful commits, documented reproduction/fix steps, and pull requests that are easy to review. I’ll also validate the critical fixes on at least one recent Android and iOS device before considering them complete, with particular attention to the reliability of the emergency workflow. If you provide the GitHub repository and current error details, I can review the codebase and prioritize the issues based on their impact on the safety-critical user journey. Regards, Nikita Gupta

Silent SOS pushes often fail at token registration, APNs/FCM routing, or background handler setup. I’ll trace the full path from SOS action to recipient device, including token refresh, payload format, permissions, and platform-specific delivery behavior. Testing will use real Android and iOS devices—not simulator-only results. Once notifications are stable, I’ll isolate the remaining Crashlytics issues, deep-link routing, and foreground/background location failures. Each fix will come in a focused pull request with meaningful commits, reproducible steps, and device verification. I’ll also check iOS background-mode entitlements and Android service restrictions that can make fixes work only while the app is open. A relevant React Native mobile project is churchsync.online. I’m available full time this week at $30/hour. Does SOS sending currently fail from your backend, Firebase Functions, or directly from the app?
