My Android and iOS builds are both having trouble talking to the back-end. The core problem is straightforward: the app fails to connect to the server reliably, so many screens never finish loading and some actions time-out. I need a developer who can jump into the existing codebases—Kotlin/Java on Android and Swift/SwiftUI on iOS—identify the bottlenecks, and implement a clean, tested fix that restores stable server communication on each platform. I will give you full access to the current repositories, the API documentation, and error logs from Google Play Console and TestFlight. Once the issue is resolved I’ll submit fresh builds to both stores; your work is complete when the new versions pass internal QA with no connection failures. Deliverables • Root-cause analysis report outlining what broke and why • Patched Android and iOS source with clear commit messages • Brief test plan (manual or automated) showing the fix in action • One post-release follow-up session in case edge-cases appear If we work well together, I have a feature roadmap ready and would love to keep you on for the long haul.

Hello, I’m Muhammad Awais, a mobile developer with solid experience in Kotlin/Java for Android and Swift/SwiftUI for iOS. I understand your Android and iOS builds fail to reliably talk to the backend, causing screens to stall and actions to time out. I will start with a fast triage of error logs from Google Play Console and TestFlight, compare them to the API docs, and reproduce the issue locally to pinpoint where the failure occurs—network layer, timeouts, retries, TLS, or backend limits. Then I’ll implement targeted fixes with minimal changes, add deterministic tests (unit or integration) for both platforms, and document each commit clearly. Deliverables include a root-cause report, patched Android and iOS source with meaningful commit messages, a concise test plan, and a post-release follow-up session to address edge cases. I’ll keep you updated and ensure the new builds pass internal QA before store submissions. Are there recent backend changes, rate limits, or authentication issues that correlate with the connectivity failures, and can you share any server-side logs or error traces from Google Play Console and TestFlight? Best regards,

I can jump in and fix this. I’ve worked on stabilizing mobile apps where unreliable API connections caused screens to hang, time out, or fail silently. I’ll: Review both codebases (Kotlin/Java for Android, Swift/SwiftUI for iOS) plus logs and API docs Identify the root cause (network layer, timeouts, SSL, auth, threading, retry logic, etc.) Implement a clean, tested fix on both platforms Provide a brief root-cause report, clear commits, and a simple test plan Stay available for a post-release follow-up in case edge cases appear Comfortable working directly in existing repos and moving quickly so you can submit stable builds to Play Store and App Store. Happy to continue long-term if this goes well. Best, Jenifer

Hi, this is Elias from Miami. I’ve reviewed your project and understand that both your Android (Kotlin/Java) and iOS (Swift/SwiftUI) apps are struggling with unstable server connections, causing screens to fail and actions to time out. The goal is to diagnose the bottlenecks, implement clean fixes, and restore reliable communication on both platforms. I have 10+ years of experience debugging cross-platform mobile apps, optimizing network layers, and ensuring stable API interactions. I’m comfortable working directly in existing codebases, analyzing logs, and producing well-tested, maintainable solutions. A few questions to clarify the scope: Q1: Are connection failures consistent across all API endpoints, or do specific calls/timeouts trigger most issues? Q2: Are you using any network libraries like Retrofit, Alamofire, or URLSession wrappers that we should focus on? Q3: Should the fix include offline caching or retry mechanisms, or only stabilize live connections? Q4: Do you want automated regression tests for network reliability added, or is a manual QA plan sufficient? I can deliver a root-cause report, patched Android/iOS builds, a short test plan, and one post-release follow-up, ensuring your apps are fully stable. Looking forward to getting this resolved quickly and cleanly. Regards, Elias

Hi, Kareem here. To restore stable app performance, the main thing to get right is identifying where the client–server contract is breaking—timeouts, retries, auth, or environment config—across both platforms. I’ll dive into your Kotlin/Java (Android) and Swift/SwiftUI (iOS) codebases alongside the API logs to pinpoint the root cause, then implement a clean, tested fix that stabilizes requests and screen loads. I’ve handled similar cross-platform connectivity issues—rate limiting, SSL/pinning, token refresh, and background threading—so I know how to ensure reliability and clear diagnostics. The best way to start is a focused root-cause analysis with a repro checklist, followed by patched builds and a concise test plan for QA. Let’s get this solid and store-ready.
