Germany

Message

At Cognizant Technology Solutions, I built Playwright automation integrated into CI/CD, reaching 85% regression coverage and cutting manual regression effort by 80%. I also supported risk-based Go/No-Go decisions, contributing to about 98% defect containment and zero critical production defects.

Across web applications and REST APIs, I performed manual and automated testing, investigated defects, and checked fixes through to closure. I contributed to test planning and traceability, and worked with Agile (Scrum, SAFe) teams on release readiness.
