Mobile App Bug Fixes and Feature Enhancements

@deepbansal1111

Hello, I have read your requirement to jump into an existing codebase and fix the critical UI and performance issues on both iOS and Android, and I can do that. I have over 8 years of experience delivering mobile apps (native and cross-platform) and have shipped 200+ production apps with backends, automated builds and store submissions. I specialise in diagnosing UI breakages across screen sizes and OS versions, tightening navigation flows, hunting down rendering glitches, and profiling/addressing performance bottlenecks with measurable improvements. I will work directly in your repository with clean, well-documented commits and meaningful branch names, produce test builds for iOS and Android that verify the fixes across common devices and OS versions, and deliver a concise changelog explaining each change and the reasoning behind it.
