RomaniaWhat I'm looking for
I am a QA Automation Engineer with extensive experience building scalable automated testing frameworks using Playwright, TypeScript/JavaScript and Java/Cucumber across UI and big data pipelines. I have architected CI/CD pipelines, implemented cross-device testing, performance benchmarking, and reduced test flakiness by 40% while improving execution speed by 30%.
My background also includes developing large-scale distributed data processing pipelines on Google Cloud Dataflow, migrating testing infrastructure from Python to Java, and delivering AI operations and support solutions. I am adaptable, resilient, and driven to design reliable, maintainable test automation that accelerates delivery and improves product quality.
