QA Tester

I am an ISTQB CTFL v4.0 certified QA Automation Engineer based in Prague. I test web applications through exploratory testing, automated UI and API checks, data validation, and performance testing. I use generative AI, agentic systems, and ChatGPT to support test design, requirements analysis, documentation, and test automation. I critically review AI-generated suggestions and validate all findings against requirements and actual application behavior. My toolkit includes Python, Playwright, Postman, SQL, JMeter, Git, Jira, and TestRail. I currently work as a Software Quality Assurance Tester at Digitální a informační agentura. Previously, I tested building automation systems at Schneider Electric and worked on freelance testing projects across different applications. I enjoy turning requirements into clear positive and negative test scenarios, investigating reproducible defects, and helping teams deliver reliable software.
