πŸ‘¨β€πŸ’» About Me

I'm an Information Technology professional with 8+ years of experience, specializing in:

  • πŸ§ͺ Web Testing & QA β€” manual and automated testing, functional/regression testing, test-case design
  • πŸ€– Automation β€” automated test suites and QA pipelines to catch issues before release
  • πŸ“Š Data Visualization & Analytics β€” turning raw data into clear, decision-ready dashboards and reports
  • 🌐 Web Development β€” building and validating web applications end-to-end

I care about quality, reliability, and insight β€” making sure software works as intended, and that the data behind it tells an accurate story.
