Senior Manual QA Engineer delivering reliable software quality for enterprises.
Costa RicaWhat I'm looking for
I’m a Senior Manual QA Engineer with 10+ years of experience delivering high-quality software for global enterprise and financial organizations. I specialize in Manual Testing, Functional Testing, Regression Testing, Web Testing, API Testing, UAT, Test Planning, Defect Management, SQL validation, and Agile collaboration—so teams can release with confidence and clear acceptance criteria.
I’ve delivered more than 95% functional and regression test coverage, reduced production defects by 30% through root-cause analysis, and supported on-time delivery by designing comprehensive manual test cases and regression scenarios aligned to business requirements. In my freelance role, I’ve performed functional and UX testing for an AI-powered translation platform with bilingual English-Spanish validation, coordinating with international stakeholders to continuously improve product quality—while keeping automation and mobile testing out of scope unless explicitly treated as optional.
