QA Tester / Transcriber

I'm a Top-Rated QA tester and Transcriber from the Czech Republic. I perform functional and usability tests on websites, desktop and mobile applications. I write well-structured test reports, find bugs which others overlook, and document them with screenshots. I also provide precise audio transcription and translation services between Czech and English. I use macOS, iOS, and Android. During my free time, I do further research in web development, programming and automation testing. I successfully completed an IT course for automated testing in Python. I can use tools such as; Git, Jira (Atlassian), PyCharm, Pytest, Selenium and Postman. I'm also building on my own domain Jophymba website in HTML and CSS to present my work and skills. I am a hardworking, responsible, and reliable person with a keen eye for detail. I thoroughly enjoy my work on Upwork and give my best to every task, no matter if big or small. Let's connect!
