ABOUT OLEKSANDR SERPENINOV

With over 6 years of experience as a Senior QA Engineer, I bring a comprehensive skill set in quality assurance and software testing to ensure the delivery of high-quality, secure, and reliable software products. My expertise encompasses a wide range of platforms, including web, mobile, and APIs, leveraging cutting-edge tools and technologies. Certified in Python Automation and Testing, I excel in automated testing frameworks such as Selenium WebDriver, Appium, and Cypress. These tools enable me to create robust and efficient test suites, streamlining the testing process and ensuring comprehensive coverage across multiple platforms and devices. At Mercari US, I spearheaded the successful launch of the Furniture shipping feature, driving significant revenue growth and user satisfaction. I also identified and resolved critical security vulnerabilities, preventing financial losses. I streamlined testing processes through automation, significantly reducing production bugs. I enjoy collaborating cross-functionally with developers, product managers, and stakeholders to gather requirements, design, and validate software solutions. My goal is to enhance user satisfaction with the product I work on through rigorous testing and continuous improvement.
