At Collibra, I refactored the test automation framework within my first month, making it easier to write autotests and reducing review and maintenance time. I also built custom Claude Code skills and AI-driven pipelines for test authoring, test case generation, and coverage review.

At Stats Perform, I designed a data quality gate that flags inaccurate model predictions before they reach customers, reducing failure investigation time by 50%. Across my QA work, I’ve built automation frameworks, integrated quality checks into CI/CD, and guided teams as a Scrum Master.
