QA Analyst — Test Automation Fluxo
I structured the QA program from scratch for six products, including a foreign-exchange platform, back-office applications built with Next.js, a .NET 8 backend, a Python service, a partner portal, and an AI copilot. I implemented risk-based test strategy, acceptance-criteria traceability, and regression policies.
I scaled CI automation to approximately 3,400 tests using Playwright E2E with TypeScript, Vitest, Testing Library, MSW, xUnit, and NSubstitute, reducing manual execution to 3.5%. I eliminated flakiness in the critical E2E suite through resilient global setup and deterministic network-response waits.
I introduced escape rate tracking, reduced production-defect rates per sprint from 83% to 20%, and corrected CI quality gates to block failed tests. I automated REST API and contract validation, validated SQL persistence, integrated Datadog Error Tracking with Azure DevOps, and built AI-supported failure classification and triage automations.
