URGENT Mobile App Bug Fixes: Android & iOS navtive

@mariakhan73700

As an experienced Mobile and Web Application Developer, I have successfully resolved critical issues in similar projects to ensure smooth running of mobile apps on both platforms. I am proficient in Java, Kotlin, Swift and my strong analytical skills allow me to independently identify problem areas while delivering precise, well-commented patches that compile without warnings. My commitment to producing high-quality work with a swift turnaround time is exemplified by my ability to work simultaneously on iOS and Android platforms for bug fixing. In terms of comparable production bug-fix work, one of my notable projects was for a large scale e-commerce application where I single-handedly fixed five critical bugs that were causing frequent app crashes. By deploying my expertise and leveraging effective communication channels like Slack, I was able to effectively assess the source code and provide clean patches with minimal disruption to the overall functionality.

I have 6+ years of experience fixing production-critical bugs in Android (Java/Kotlin) and iOS (Swift) apps. I can jump into the codebase immediately, trace root causes independently, and ship production-ready fixes. I’ve handled TestFlight-only crashes, memory/state issues, and hard-to-reproduce edge cases in live apps. I’ll commit clean, well-commented patches, ensuring no performance regression or new issues. I’m comfortable collaborating via Slack, quick calls, and direct backend coordination. I can start immediately, share relevant bug-fix examples, and provide a clear time/cost estimate.

Hello, I can jump into your codebase immediately and resolve the five high-priority bugs across both Android (Java/Kotlin) and iOS (Swift). I’m comfortable working independently in unfamiliar code, tracing root causes rather than applying surface fixes—especially for critical issues like iOS crashes that slip past TestFlight. I’ll diagnose each issue methodically, implement clean and well-commented patches, and ensure the fixes introduce no regressions or performance impact. I’m used to working with limited documentation and collaborating closely with backend teams, so Slack coordination and quick video calls work well for me. Once fixes are pushed, I’m happy to walk you through the changes in a short review call. Earliest start: Immediately Pricing: Open to a flat quote or hourly with a capped total—happy to align with your preference I’ve handled similar production-level bug fixes under release pressure and can share relevant examples if needed. Ready to start today and help unblock your release. Best regards, Rajni

@quantalynktech

These release-blocking Android & iOS bugs are exactly the kind of issues I fix regularly. I’ve worked on production mobile apps where stability and zero regression are critical before a release. Based on your description, this involves tracing crash points, fixing root causes (not patches), and validating performance on both platforms. This should take approximately 3–4 hours of focused work once I review the codebase. I can deliver clean, well-commented commits and verify no regressions before release. The bid amount is indicative. I’ll confirm the final quote after reviewing the repository and clarifying the exact scope. Quick question: do you already have crash logs / stack traces for the iOS TestFlight issue, or should I reproduce it from scratch? I work strictly via Freelancer milestones and can start immediately.

@SashaDev1

Hello, With deep expertise in both Android and iOS development, I assure you a highly efficient service, fixing the crucial bugs, and expediting your mobile app release. My prior experience includes taking ownership of complex bug-fixing projects similar to yours - identifying root causes, commissioning clean patches verified for performance, without any regression. To cite a comparable project, I was lead engineer for rectifying twenty easily-overlooked bugs in an API-dependent food ordering app. I take pride in my transparent communication with clients to deliver tailored solutions that align with their goals. You can count on me for swift response times and effective troubleshooting, even when navigating through undocumented codebases. On detecting unavoidable ambiguities, I'd promptly initiate a video call to get direct clarifications from you and ensure uninterrupted progress. To address your immediate needs, I'm willing to begin work immediately. While providing a flat quote or an hourly estimate können wir sicher einen gerundeten Wert vereinbaren to abide by the budget cap. Once I am done fixing these issues, I'll guide you through the changes on a brief call so that you can easily review my work before pushing it to the rep. If you're ready to bring me onboard today, let's dive right in and elevate your mobile app's performance together! Thanks!
