Currently, I work with TikTok, where I perform manual testing of payment systems across mobile and desktop platforms.

I document test results, report issues, and provide feedback to improve platform performance and reliability. I have also worked with companies such as Axenic Global IT Solution and Bemobi, conducting network performance testing, subscription testing, and mobile app usability testing. In addition, I have participated in AI application testing projects, including conversational AI and voice-based applications such as Loora Beta (via TestFlight). My experience also includes content proofreading, UI validation, and mobile app visibility testing for fintech and credit applications, ensuring accuracy, clarity, and proper functionality across different user flows.
