I am a highly passionate and skilled Tester, with extensive expertise in testing web, mobile, and desktop applications. ♛ Upwork`s certified Top Rated Plus QA freelancer. ♛ Listed among TOP 1% of Successful Upwork Freelancers with a perfect "100% Job Success" Badge. Expert in QA, QA....and QA 😊 ♛ 7000 + hours of exclusive Software Quality Assurance, Website Quality Assurance, App Testing experience on Upwork (5 STAR rating) and 9+ years of corporate experience in the field of QA and testing software. I absolutely love what I do and I thrive on paying close attention to detail and discovering many bugs ranging from basic grammar errors to critical functionality bugs. I never look at testing as a tedious job, I look at it as a riddle that I need to discover the many solutions. I am often praised for my highly detailed, easy to follow defects, test scenarios, test cases and test plans. I am experienced at writing automation test scripts in Java, C# with Selenium, TestNG, Junit and TestNG and Cypress. I am very thorough with my manual and automated test scrips. I understand the difference between an “okay test case” and an “exceptional test case”. If a script breaks, or a test case fails, I can quickly locate where the error occurred and respond accordingly. Each automated test case I create also contains two separate reports: A log file, for development purposes and a Test Result Report for end uses who aren’t familiar with technical jargon. I’ve successfully written manual and automated scripts for many different types of websites from e-Commerce and CRM Management to social media and dating sites. One of my strengths includes my exceptional leadership ability. When I am not writing automated scripts, I enjoy working on building QA teams from scratch and training people that are unfamiliar with QA before bad habits are developed.
