Description

I help companies release stable, reliable digital products by identifying critical issues early and protecting the end-user experience. I am a Senior QA Engineer with over 7 years of hands-on experience in manual, exploratory, and regression testing across mobile (iOS/Android), web, and API-driven systems.

My background is in complex, real-world environments where quality matters: onboarding flows, backend integrations, payment-related logic, connected devices, and production-critical releases. I work closely with developers, product managers, and designers in Agile teams, acting as the voice of quality and risk prevention throughout the development lifecycle.

I focus on what truly matters: clear test coverage, meaningful defect detection, precise reporting, and release confidence. Clients value my reliability, structured thinking, and ability to anticipate issues before they reach users.

Typical deliverables include test strategy support, manual and exploratory testing, detailed defect documentation, regression validation, and release readiness assessments.

Available for high-quality freelance QA missions (10–20 hours per week).

Remote-first. Based in Zurich, Switzerland.
