About this gig

Is your AI project or mobile app ready for real users?


I will professionally test your AI software, Android app, iOS app, or mobile application to identify bugs, broken features, UI problems, usability issues, and unexpected behaviour before launch.


My QA testing service can include:

  • AI project testing
  • Mobile app testing
  • Android & iOS testing
  • UI and feature testing
  • Functional testing
  • Manual QA testing
  • Unit testing review
  • Code review
  • Usability testing
  • Regression testing
  • Bug identification and reporting
  • Screenshots and screen recordings


You will receive a clear and organized testing report showing the issue, severity, affected feature, steps to reproduce, expected behaviour, actual behaviour, and supporting evidence where applicable.

.

Whether you are developing an AI tool, SaaS application, mobile app, or software product, I will help you identify problems and improve the user experience before your customers encounter them.


Send me your project details before ordering, and let's get your product tested.
