Cross-Platform Mobile App QA Testing

I'm in need of a skilled QA tester who has prior experience with BrowserStack/lambdatest and Appium automation testing. The purpose of the project is to test a cross-platform mobile application. The application is intended to be compatible with both iOS and Android platforms.

Key Requirements:
- Experience with cross-platform mobile application testing is highly preferred
- Proficiency in using BrowserStack for testing
- Proficiency in using Appium for automation testing

I'm not looking for any specific functionalities at the moment, just a thorough QA testing of the app on both iOS and Android platforms. The project has no strict deadline, so you can work at your own pace, but a timely completion is obviously preferred.

Ideal skills and experience for this job include:
- Proven experience with BrowserStack and Appium
- Previous QA testing experience with cross-platform mobile applications
- Strong attention to detail and problem-solving skills
