I've worked for a few years now here and on Upwork.com, and been involved in developing and working on many interesting projects like websites, and apps & games for several platforms. I have the experience and breadth of skills to tackle many software development projects from things I am familiar with (Unity games & apps, web pages - React is my fav frontend, Flutter apps), to even things I may not have direct experience with at the moment. I learn quick, listen well, and always try to deliver good quality results. If it's software development related, I can probably do it. moins -

During this project, I identified multiple high-impact system issues such as AI failures, session breakdowns, data inconsistencies, and mobile workflow crashes. My testing approach goes beyond execution—I actively think like a real user, explore edge cases, and try to break the system to uncover hidden defects before users do. What I specialize in: Functional & Regression Testing Mobile App Testing (iOS / Android) AI-based Application Testing API & Backend behavior validation (basic level) Exploratory Testing Bug Reporting & Test Documentation Key Project Experience AI Interview Mobile Application – QA Testing Project I conducted comprehensive QA testing on an AI-driven interview preparation mobile app designed to simulate real interview scenarios using AI-generated questions, feedback, and voice interaction.
