Back to original languageAbout André
As an external QA engineer, I am available for projects starting immediately – remote, flexible, and ready to go.
Many teams struggle with the same issues: unclear test cases, insufficient test coverage, too much manual effort, or a lack of QA capacity.
I support companies in noticeably relieving their quality assurance – through clear test cases, reliable automation, and structured QA processes.
As an ISTQB-certified Test Engineer with experience in manual testing, automated testing, and test coordination, I bring both technical and organizational strengths.
🔹 What I solve
– No or unclear test cases → I create structured, traceable Test Cases & Test Suites
– Too much manual effort → I automate meaningful test areas (Playwright / Cypress)
– Lack of QA resources → I take over manual tests & Exploratory Testing
– QA without structure → I define test strategy, prioritization & review processes
– Insufficient coordination → I manage external testers and ensure clear workflows
🔹 My services
– Creation & maintenance of manual test cases (Web, Mobile, API)
– End-to-End & API test automation
– Review & optimization of existing test cases
– Setup or improvement of test frameworks
– Coordination of external / internal testers
– Test management, reporting, prioritization
– CI/CD integration of automated tests
🔹 Strengths
– Very structured approach & high traceability
– Clear communication with developers & product owners
– Combination of hands-on testing + automation
– Quickly deployable, flexible, reliable
💬 I am happy to support you on a project basis or as a long-term external QA partner – to make your releases more stable, faster, and less risky.
