🏆 8+ years in QA — 180+ releases shipped across web, mobile, desktop and API 🐞 4000+ test cases automated · 1000+ bugs reported · fintech, SaaS, e-commerce, healthcare 📋 ISTQB certified · Google Associate Cloud Engineer · GenAI for Software Testing 📱 Real device lab for mobile and desktop — you get results from real user behaviour, not emulators Flaky tests, slow regression, bugs reaching production? That is what I get hired to fix. I cover the whole range: manual and exploratory testing where judgement matters, Playwright and WebdriverIO automation where repetition does, and Postman for the API layer underneath both. 🚀 What I can do for you 🔹 Test automation in any framework and any language — Playwright, WebdriverIO, Cypress, Appium, Selenium, Swift and XCUITest — running on real devices or in Firebase Test Lab 🔹 API testing and contract validation with Postman, Newman and OpenAPI schema checks 🔹 Mobile, web and desktop application testing on real hardware, not emulator screenshots 🔹 Manual, exploratory and regression testing when there is no documentation to start from 🔹 Wire all of it into CI so tests run on every pull request instead of before every release 🛠 Stack ✔ Programming languages: TypeScript, JavaScript, Python, Java, Swift, Bash ✔ Automation frameworks: Playwright, WebdriverIO, Cypress, Appium, Selenium, XCUITest ✔ API and performance: Postman, Newman, k6, JMeter, BlazeMeter, Checkly ✔ CI/CD and reporting: GitHub Actions, GitLab CI, CircleCI, Allure, Monocart, Grafana ✔ AI and LLM: Anthropic Claude, Langchain, custom MCP servers ✔ Infrastructure: Docker, Kubernetes, Linux, AWS, GCP 🎓 Certifications • ISTQB — software testing • Associate Cloud Engineer, GA4 — Google • GenAI Tools and AI Agents for Software Testing • People Management — Google • Agile Fundamentals & PSM 📱 Devices I test on • iOS: iPhone 15 Pro, iPhone 13, iPhone 12, iPad 9th generation • Android: POCO F9 Ultra • Desktop: MacBook Pro M4, high-spec Windows 11 desktop, Linux • Cloud: Firebase Test Lab and BrowserStack, cross-browser coverage on Chrome, Firefox, Safari and Edge 💡 Recent results ✅ Czech fintech payments platform (SEPA, SWIFT, FX): ran the QA audit, wrote 600+ test cases and automated 305 in Playwright and TypeScript. Manual regression down 60%, 100+ critical bugs caught before release. ✅ Australian booking platform: automated 4000+ API test cases with Postman, Newman and Allure across staging and production, reported 600+ bugs. ✅ UK AI-meeting SaaS, two weeks from launch with no QA: exploratory passes across roles, devices and browsers found 60+ bugs, 15 critical. All closed pre-release, post-release critical defects went to zero. I do not start from an empty repository. I keep ready-made automation templates for different languages and platforms — web, mobile, desktop and API — so your first tests are running in days instead of weeks. 📩 Tell me what is breaking Send me a message with your stack or your worst QA bottleneck.
