At Hilti Deutschland, I defined QA strategy for four IoT cloud product teams and designed and coded the core Playwright/TypeScript and pytest framework. I also established automated evaluation workflows for RAG/RARAG applications, assessing response accuracy, groundedness, hallucination risk, and quality drift.
I introduced AI-assisted QA workflows with Claude and Copilot, reducing test design and automation development effort by about 40%. By increasing automation coverage from 30% to 85%, I helped cut regression test cycle time by 60% and improve release cadence from eight weeks to four.
Earlier, at reev GmbH, I built a TypeScript automation framework for web, backend, and mobile testing. At zooplus AG, I developed Java, Selenium, and Appium framework libraries and parallel CI execution that reduced end-to-end regression from three days to under six hours.
