Hi, I'm Marc. I am an experienced Software Quality Assurance Analyst with expertise in manual testing for web, mobile, and desktop applications. I also have experience in writing highly detailed test scenarios, test cases, and test plans. 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 see it as a riddle that I need to discover the many solutions. My specialized test methodologies include regression testing, acceptance testing, UI/UX testing, functionality testing, system testing, and performance testing. I also possess experience writing automation test scripts in C# with Selenium and NUnit.
