What I'm looking for

I’m looking for a QA role focused on backend and API testing, where I can strengthen Python automation (pytest, API scripting), deliver release-ready coverage, and partner with developers and analysts to validate complex business logic end-to-end.

I’m a QA Engineer with 4+ years of hands-on experience testing high-load enterprise systems in retail, logistics, and e-commerce. I specialize in backend, API, and integration testing, validating complex business logic across warehouse, marketplace, and freight-cost platforms. I deliver test coverage and release support across Scrum/Kanban teams, collaborating closely with developers and analysts.

In my current role, I reduced inventory discrepancy errors by validating product-transfer logic end-to-end across 3 integrated warehouse modules, catching 15+ critical defects before each production release. I’ve maintained zero critical regression in bi-weekly releases by designing regression suites for inventory accounting and equipment integration, and I accelerated defect resolution by 20% by standardizing Jira bug-report templates. Previously, I improved tariff-calculation accuracy by identifying 12 routing-logic defects in the freight cost engine and cut test-run preparation time by 30% with standardized documentation and a reusable Confluence test-case library—while also leading validation of 4+ third-party API connections in marketplace integrations.
