What I'm looking for

I’m looking for a QA role where I can collaborate closely with Engineering and Product, protect production with strong exploratory/regression discipline, and grow into test automation (Playwright/TypeScript) while working in Agile teams.

I’m a QA Engineer with 7+ years of experience testing e-commerce platforms, mobile applications (Android/iOS), APIs, and enterprise logistics systems. I’m ISTQB certified and focused on finding critical production defects through exploratory testing and log analysis across event-driven pipelines.

I’ve built trust with Engineering and Product teams across the full software lifecycle in Agile environments, using tools like Postman, Jira, Azure DevOps, BrowserStack, AppDynamics, and Kibana/ELS. In high-impact moments, I traced issues to root cause—like identifying a CMS performance problem tied to query timeouts and validating the fixes through targeted regression and performance testing.

I also bring strong test automation momentum, currently building test automation skills with Playwright and TypeScript. From load testing with JMeter to validating SFTP workflows and REST API endpoints, I consistently add coverage where it matters most, including regression prevention, cross-platform E2E releases, and BDD/Gherkin scenarios driven by Product Owner acceptance criteria.
