Worked on the Zeny project as a QA tester focused on exploratory testing and real user behavior analysis. My goal was not only to find bugs, but to evaluate the product from a UX, logic, and usability perspective. Responsibilities included: — exploratory testing of the mobile application — identifying UI/UX, functional, and logical issues — testing user flows and edge cases — validating real-life usage scenarios — creating detailed bug reports — writing clear reproduction steps for developers — recording screen videos demonstrating issues — preparing structured QA reports in Notion based on the client/team workflow — documenting bugs with screenshots, expected vs actual behavior, and additional notes Because I also develop mobile apps myself, I understand the product from both the QA and developer side — including app logic, technical limitations, and how to communicate issues in a way that is actually useful for the development team. The example below demonstrates both the structure of the full QA report and a detailed breakdown of one issue, including reproduction steps, expected/actual behavior, impact analysis, and visual references for the development team.
