Still searching for an experienced QA Tester, QA Engineer, Security Engineer, or Penetration Tester? Let’s save your time and talk 😉

I’m a QA Tester / QA Engineer with 10+ years of experience in manual testing, QA automation, security testing, penetration testing support, and overall product quality assurance across web, mobile, SaaS, fintech, healthcare, cybersecurity, AI/ML, and enterprise platforms.

I help teams test faster, release with confidence, automate repetitive testing processes, and catch critical bugs, security risks, and performance issues before they reach real users.

My work combines a strong QA mindset with practical Automation, Playwright expertise, API testing experience, and a security-focused approach. I don’t just click through screens and report obvious issues — I analyze how the product behaves, how the system is built, where integrations may fail, and where vulnerabilities may hide.

✅ Tools and Libraries

✔ QA Automation: Playwright, Cypress, Selenium, Appium
✔ API Testing: Postman, REST Assured, Supertest
✔ Security Testing: OWASP ZAP, Burp Suite, DevTools, custom scripts
✔ Performance Testing: JMeter, LoadRunner
✔ CI/CD Integration: GitHub Actions, GitLab CI/CD, Jenkins
✔ Bug Tracking & Test Management: TestRail, Zephyr, Jira, Trello, TestomatIO
✔ Reporting: Allure, Mochawesome
✔ Accessibility Testing: axe-core, Lighthouse, manual accessibility review
✔ Version Control: Git, GitHub, GitLab, Bitbucket

✅ Certifications and Experience

📌 ISTQB Certified QA Tester — strong foundation in QA methodologies, structured test design, test planning, test execution, and quality processes.

📌 Security-Focused QA Experience — practical experience with security QA testing, penetration testing support, vulnerability validation, OWASP-based checks, and secure product delivery.

📌 Domain Experience — Fintech, Cybersecurity, Healthcare, Marketing, Construction, Telecommunications, Real Estate, AI/ML, Logistics, E-commerce, SaaS, and 20+ other industries.

📌 QA Leadership — mentoring junior testers, building QA automation workflows, improving test strategies, preparing detailed test plans, and setting up scalable QA processes for complex products.

📌 Automation Expertise — hands-on experience building automation frameworks, especially with Playwright, Cypress, Selenium, and Appium, to support fast and stable product releases.

✅ What I’ve Been Responsible For as a QA Tester / QA Engineer

• Manual QA Tester: validating product flows, business logic, UI behavior, and edge cases
• Automation Tester: building stable and maintainable automation frameworks
• Playwright Automation Engineer: creating end-to-end test suites and cross-browser automation
• API QA Tester: validating endpoints, integrations, authentication, and secure data flow
• Security Engineer: identifying risks, testing access control, and supporting safer releases
• Penetration Tester: checking web applications for common vulnerabilities and security gaps
• Cross-Browser QA Tester: ensuring smooth behavior across browsers, devices, and screen sizes
• Accessibility QA Tester: using manual checks and tools like axe-core to support compliance
• Mobile QA Tester: full-cycle mobile app test coverage for iOS and Android
• Regression QA Tester: protecting existing functionality during new releases
• Performance QA Tester: checking speed, load handling, and system stability

✅ How I Can Help Your Team

I can help you:

• Find critical bugs before your users do
• Set up QA automation from scratch
• Improve existing Playwright, Cypress, or Selenium tests
• Create regression test coverage for fast-moving products
• Validate APIs, integrations, and backend logic
• Support security testing and penetration testing efforts
• Improve release quality and reduce production issues
• Build clear QA documentation and test plans
• Integrate automated tests into CI/CD pipelines
• Make your product more stable, secure, and user-friendly

Whether you need a QA Tester, QA Engineer, Automation Tester, Playwright expert, Security Engineer, or Penetration Tester, I can step in and help your team ship with more confidence.

Let’s connect and discuss how I can help improve your product quality, QA and automation coverage, and security testing process.
