Kateryna S.
ISTQB Certified Manual/Automation QA Engineer | Web & Mobile Testing
ISTQB Certified QA Engineer I’m a QA Manual/Automation Engineer with 4+ years of experience, focused on building reliable automated tests as well as doing repetitive manual work. I mostly work with Playwright and help teams set up test automation that actually fits into their development process — not something that breaks every other day. 🚀 What I usually do: • Build end-to-end tests using Playwright (TypeScript / JavaScript) • Set up and improve test automation frameworks • Integrate tests into CI/CD (GitHub Actions, GitLab CI, Jenkins) • Run tests in Docker when needed • Fix flaky tests and make them stable • Help teams understand what should (and shouldn’t) be automated 🧠 About AI-related features: I’ve worked with products that include AI features (chatbots, recommendations), where testing isn’t always straightforward. • I focus on edge cases • validate outputs and data consistency • and automate the parts that actually make sense to automate 🛠 Tech I use: Playwright, TypeScript / JavaScript REST APIs GitHub Actions / GitLab CI / Jenkins Docker Postman, Git ClickUp, Jira 💡 How I work: I don’t just “write tests” — I try to build something that saves time long-term. That usually means fewer but better tests, clear structure, and making sure everything runs reliably in CI. 📩 If you’re looking for someone who can: • analyze your application/website (UX, usability, errors, edge cases) • provide detailed bug reports and structured checklists based on analysis • suggest clear improvement ideas and optimization opportunities • set up test automation from scratch • clean up a messy test suite • make your tests more stable and reliable feel free to reach out.
