Profile: 9+ years of experience in Software Testing which includes understanding the system under test and functional requirements, and creating the needed test assets to perform necessary functional and non-functional testing. My recent experience was working as a QA with Virtual Presenz Inc. and I had worked with Multi National Organisations like Accenture, Herbalife and Misys. I have also contributed to the Steller Payments as a freelancer through Upwork. I have worked in Agile software release eco-system, staying up to date with daily scrum and give clear status about my work on what’s completed, what’s that I would be working on and what’s blocking my current work deliverables. Raising risk at the right time and highlighting the severity of the issue is something I believe is a must and strong skill a QA should possess, which helps the team to set proper priority around the issue. I am currently working as a QA Engineer at Virtual Presenz Inc., where I ensure system compliance with stringent safety standards through automation testing using Python and Selenium.Beyond QA, I have experience working with AI microservices, integrating them into web dashboards to display security analytics metrics, including Crowd Analytics, Weapon Detection, and Environment Analytics. I have also contributed to basic UI development by:Writing efficient, testable code using Flask and Python best practices.Developing responsive user interfaces with Material Dashboard and HTML/CSS. Before that I have experience working with eCommerce organization , where I was tasked to maintain the end to end software quality of an eCommerce Distributor Administration web application, which is hosted in a cloud eco-system. Prior to that I have experience in working with Business and Finance domain. These are some of the testing tools I’m proficient in but not limited to, Quality Center, Test Foundation Server and Jira including Tracking, Traceability, Execution, Reporting and Management. I enjoy working very closely with Business Analysts, Product owners, developers and my QA peers for proper understanding of the Product functionality and its nuances to test the application in maximum possible detail but also be efficient with my time. I have created detailed status reports and templates to inform the stakeholders about the daily progress and risks/dependencies with other teams. Succesfully completed Prompt Engineering Certification – edX in 2025 Completed Python Programming course from Harvard University in 2018 Work status: Currently on Employment Authorization to work in the United States and I do not require Visa Sponsorship, however my nationality is Indian.
