Experienced Mobile App Developer Needed for Android Updates, iOS Conversion, Google Play Upload

I'm looking for a reliable and skilled freelance mobile app developer to help enhance and expand my existing app called WhatsLook.

The app is already built for Android and focuses on content discovery and sharing (similar to the website , which allows users to submit and explore news, images, videos, polls, lists, quizzes, and music with features like sorting by popularity, voting, and commenting).

Unfortunately, my previous freelancer (from Pakistan) wasn't up to the task—they agreed to all requirements but didn't deliver quality work.

I need someone professional who can commit to completing the job properly without overpromising.

Specific Tasks:

Amend the Existing Android App:

Make necessary updates and improvements to the current Android version. This includes bug fixes, UI/UX enhancements, and any minor feature additions based on my detailed specs (to be provided).

Convert the App to iOS:

Port the Android app to iOS, ensuring full compatibility, smooth performance, and adherence to Apple's guidelines. The iOS version should mirror the Android functionality.

Upload/Update on Google Play:

Assist with preparing and uploading the updated Android app to Google Play Store, including handling any review processes, metadata, screenshots, and compliance requirements.

Contract duration of 1 to 3 months.

Mandatory skills:

Firebase, Android, Mobile App Development, Flutter
