Hi there, I have read your project requirements. You need an experienced mobile app developer to support your existing application during the testing phase, resolve bugs and issues, improve stability and performance, and continue with future feature development and maintenance. We have experience in Android application development, Java, Android SDK, Android Studio, API integrations, bug fixing, performance optimisation, and long-term application maintenance. We can quickly review the existing codebase, identify issues, implement fixes, and provide ongoing support for future enhancements. A few questions: ============= Is the application developed in Java, Kotlin, or a hybrid framework? Do you have a list of current bugs/issues and testing reports available? Will future development include new features only, or are backend/API changes also required? Do you use GitHub, GitLab, or another version control system for project management? Best Regards, Srashtasoft Team

In testing-phase Android apps, the real risk isn’t individual bugs but an unstable architecture where fixes create new regressions and slow future development. I’ve worked on Android projects focused on stabilizing codebases, isolating crash sources, and restructuring components so updates don’t break existing flows, keeping iteration smooth during active testing and beyond. Is there a crash reporting or logging system already in place, and how modular is the current codebase for future feature work?

Hi there, I have carefully reviewed your project details, and I am confident I can help you stabilize your application and prepare it for its next phase of development. I specialize in Android development and have extensive experience in debugging, refactoring, and implementing new features within existing codebases.

I can join during the testing phase to identify, troubleshoot, and resolve application issues while ensuring existing functionality remains stable. Along with bug fixing, I can support ongoing feature development, performance improvements, API integration updates, and release preparation as the product evolves. A couple of questions: Is the application built natively in Android (Java/Kotlin) or does it include a web/admin backend as well? Do you currently have a bug tracker or list of known issues that need immediate attention? I can start by reviewing the current build, reproducing reported issues, prioritizing fixes, and establishing a clear workflow for future development and maintenance. G
