What I'm looking for

I’m looking for QA roles combining manual and automation testing, with strong ownership of product quality. I want to collaborate closely with developers and product teams, and use Playwright/UI+API automation and AI-assisted workflows to improve efficiency.

I’m an automation-focused QA Engineer with 4+ years testing web applications in Agile, product-based environments. I build and maintain UI and API automated test suites using Playwright and TypeScript (plus Supertest), with a strong foundation in manual testing, API testing (Postman, Swagger), and performance testing (JMeter).

In my roles, I contribute to test strategy discussions, maintain test frameworks and documentation, and collaborate closely with developers and product teams to reproduce bugs, verify fixes, and improve QA workflows. I also leverage AI tools like Claude and Cowork to accelerate test case creation, support exploratory testing, and improve overall testing efficiency.
