What I'm looking for

I seek a role focused on test automation and CI/CD where I can build scalable frameworks, improve QA workflows, and collaborate in Agile teams.

I am a QA automation engineer experienced in building and maintaining C# and JavaScript-based test frameworks, integrating suites into Azure DevOps and Jenkins, and validating web and mobile applications across browsers and devices. I deliver scalable parallel test runs, data validation with SQL, API debugging, and concise bug reports using Jira.

I quickly adopt tools like Playwright and TestRail, author test cases, and create Python utilities to automate QA workflows. My background includes frontend engineering work with React, hands-on CI/CD experience, and a Computer Science degree earned with honors.
