I'm a self-taught QA Engineer with frontend development knowledge.
I enjoy testing web and mobile applications, identifying edge cases, improving user experiences, and understanding how products behave under real-world conditions.
Alongside QA, I've spent several years learning frontend development with JavaScript, TypeScript, and React, which helps me better understand application architecture and communicate effectively with developers.
On my GitHub, you'll find:
- QA-related projects, test documentation, and testing experiments
- Frontend projects built with modern web technologies
- UI implementation challenges and coding exercises
- Clear project documentation and setup instructions
