What I'm looking for

I seek a QA role where I can lead testing efforts, improve QA processes, collaborate with cross-functional teams, and contribute to reliable, high-quality releases.

I am a Quality Assurance professional with progressive experience testing web, mobile, tablet, and backend systems across multiple industries. I design and execute detailed test plans and cases, perform API and functional testing using tools like Postman and Insomnia, track defects with JIRA, and collaborate closely with developers and product teams to ensure reliable releases.

My background includes creating master test plans, maintaining test artifacts, supporting deployments, and improving QA processes and workflows. I bring strong troubleshooting skills, proficiency with TestRail and Microsoft Office, familiarity with Android development tasks, and the ability to work effectively in multicultural environments.
