I’m a Manual QA Tester from Brazil, focused on testing websites and applications across mobile and desktop devices. I have experience identifying bugs, usability issues, interface inconsistencies, navigation problems, and performance issues across different platforms. I perform exploratory and functional testing, UI/UX validation, and detailed QA reporting with screenshots, clear reproduction steps, and actionable feedback to help improve product quality and user experience. I also design and develop websites. I’m the founder and creator of Gargalix, a SaaS platform that I developed and continuously test and improve. This gives me hands-on experience with web development, UI/UX, responsive design, user flows, debugging, and QA from both a developer and tester perspective. I’m comfortable working with different workflows and always prioritize quality, deadlines, clear communication, and user experience.
