Hello, I'm a Mobile developer with expertise in both Android and IOS development. My work history closely matches your requirements, as most of my past projects have involved working on already developed apps to update the SDK level, add/enhance features, fix crashes and bugs, and update deprecated libraries. This experience demonstrates my ability to efficiently work on and navigate existing codebases. You can see on my profile reviews for similar jobs that I was able to finish efficiently and on time. I will be able to provide a quick turnaround time to get the app up and running in no time I have been working for the past two months on a similar job where I make changes and fixes to an already developed Android application, where I was also working remotely on a MAC device, and I was able to get the app to a final and release-ready version. As my work history you can see that I specialise in fixing build errors which will make me the perfect fit for this job. I had been working with a client for the 4 month on fixing his very complex android application where I was able to get it to a final version, during those 4 month I have shown complete dedication to deadlines and I was able to provide very high code quality, I have shown my skills in my previous job thats why our collaboration extended to other projects other than the android app which were a flutter admin panel as well as a complete refactor to the backend. I look forward to working with you.

Good Day Mubashar, Can you share your existing source code repositories (or confirm if they’re complete and buildable) along with your current Gradle/AGP and Swift/Xcode versions? I’ll audit and update both Android and iOS projects to the latest stable tools, fix compatibility issues, and test on devices for stability. Finally, I’ll deliver release-ready APK/AAB and IPA builds with updated project files and deployment instructions. Instead of maintaining two separate native codebases, I’d suggest rebuilding with a cross-platform framework like Flutter or React Native, which ensures a single codebase for both iOS and Android. This reduces long-term maintenance, speeds up updates, and keeps dependencies consistent. We can still deliver native-like performance while future-proofing your app. To understand your need: ./Do you already have developer accounts set up for Google Play Console and Apple Developer Program, and should we handle the full submission or just provide the signed builds? ./Are there any third-party SDKs (Firebase, analytics, payment gateways, social logins, maps) in your apps that may also need upgrading or reconfiguration? I'd love to discuss the project more via a call and ensure the solution is tailored to your exact operational needs. Bid amount and timeline are placeholders. Warm Regards, Taqi (ss)
