About

Professional summary

I am a Senior Test Automation Architect with more than 20 years of B2B consulting experience across FinTech, gaming and lottery, insurance, e-commerce, and transportation domains.

I specialize in AI-driven and agentic testing, including GenAI API validation, LLM evaluation, prompt testing, RAG pipeline testing, and multi-agent orchestration. I design systems that map service dependencies, configure agent behavior, and validate complex API ecosystems.

I have extensive hands-on experience building automation frameworks with Playwright, Selenium, Cypress, Karate, REST Assured, Appium, WebdriverIO, Robot Framework, and Python. My work includes web, mobile, API, database, performance, security, and visual testing.

I have delivered cloud-native Testing as a Service solutions on AWS and Azure using Docker, Kubernetes, Terraform, Jenkins, and GitHub Actions. These implementations have reduced provisioning time from days to hours and lowered manual configuration effort by 40–60%.

I have led QA automation teams, defined framework architecture, established test-data strategies, and implemented CI/CD pipelines. I am experienced with Agile, BDD, ATDD, TDD, SAFe, V-Model, and Waterfall delivery methodologies.

I am based in Vienna, Austria, hold an RWR+ work permit, operate as a freelance/self-employed legal entity, and am available to start immediately.
