What I'm looking for

I am seeking a senior QA role where I can lead testing efforts, build automation suites, improve release quality, and work in an Agile team that values security and continuous delivery.

I am a Senior Software QA engineer with extensive experience in manual and automation testing across web, API and backend systems. I have led production release testing, designed and executed test cases and automation suites using Playwright+TypeScript and Selenium, and performed penetration testing with OWASP ZAP while working in Agile environments.

I bring strong skills in API testing (Postman/SoapUI), database validation with Microsoft SQL and Oracle fundamentals, CI/CD tooling (Jenkins, Git/GitLab), and test management (Azure, Spira, JIRA). I have experience mentoring new resources, coordinating cross-border projects, and estimating and planning test strategies to ensure reliable, secure releases.
