    I am a highly focused QA Manual Tester with more than 4 years of experience in this field of research. With a good eye for detail, and being a true team player, I helped more than 10 clients to develop and make their apps perfect for a market place. Being on "the field" and making accurate reports save the time to developers and app owner. While working on Upwork as an applications tester, my task was to look for bugs, explain in writing about them to the developers, and do test cases to help them solve the issue quicker. I was also looking for cosmetic issues, report issues, etc, testing of Installation, Login, and Creation of user profile. Depending on the topic (bug) I was looking for, I have learned to check every part in detail and look at every "corner" for a potential problem. My motto was to ask a client what exactly he wants, and what type of requirements I need to fulfill. I enjoyed exploring different kinds of apps- My Hobby Courses APP, Uomini APP, etc. On a daily level, 10 to 15 bugs were found and explained to the team and devs. My second project as Quality Assurance was for CEEDO Technologies. I was testing for two products MalwareLocker and Ceedo Vault. Testing was on Win 7x32, Win 8.1x32, Win 10x32, Win 7x64, Win 8.1x64, Win 10x64) and I was looking for issues of Smoke, Functional, Acceptance, and Regression test. Testing with various malware and viruses on different Windows operating systems in real-time, or with VMware Hypervisor which enables the virtualization of practically any x86 or x64 architecture. Due to working on these projects, I have learned to be organized, methodical, and with a keen eye for details. Understanding client requirements and communicating the progress of projects are core values in achieving long-lasting business relationships. I enjoyed being a part of a vibrant and leading organization and creating footprints as a Quality assurance Engineer, assisting organizations in all aspects by utilizing all my skills, knowledge, abilities, and experience with a balance of hands-on, management, and leadership responsibilities. I am eager to continue my progress in this field of research and be a part of the team who will not only achieve their goals, but go beyond. I am available for 30 hours per week. Cheers!
