I’m a Software QA Engineer with 3.5+ years of experience delivering quality for high-load web platforms, REST APIs, backend services, and microfrontend applications. I combine manual testing, API validation, and JavaScript-based automation to keep releases stable.

In my current role, I own end-to-end testing for a high-load enterprise CMS with weekly production releases. I validate UI, backend, REST APIs, authentication, permissions, and complex business logic, and I develop and maintain JavaScript backend automated tests.

I also focus on fast, reliable defect investigation. Using Kibana logs, I investigate production issues and collaborate with developers to resolve root causes, while contributing to requirement refinement, test planning, and release validation.

Earlier, I executed functional, regression, smoke, and integration testing across multiple web products, including cross-browser and mobile compatibility via BrowserStack. I also built Python automation for marketplace integrations and use AI-assisted workflows (Cursor, ChatGPT, Codex, Ollama) to accelerate testing and engineering.
