I’m a Senior QA Engineer with 5+ years of experience in manual and automated testing for web and mobile applications. I specialize in building QA processes from scratch, designing test strategies, and ensuring product quality throughout the entire SDLC/STLC lifecycle.

I’m hands-on with test automation using Selenium WebDriver (PHP) and Playwright with Pytest (Python). With an automation-first approach for new functionality, I’ve achieved high regression coverage (around 95%) and reduced manual testing effort, while integrating tests into CI/CD workflows.

In my recent work, I’ve led quality assurance activities for enterprise-level products as the primary QA owner. I’ve run the full spectrum of testing—functional, regression, smoke, API (REST & SOAP), database (SQL), load testing (k6), and UAT—supporting reliable launches across 4 global regions, collaborating closely with engineering, product, and design teams in Agile environments.

Earlier, I worked in integration testing at Tele2, validating high-load enterprise services for more than 7 million active users. I wrote and ran complex SQL queries for data integrity and back-end logic, performed SOAP API testing with SoapUI, and supported integration testing by deploying and configuring test environments across multiple connected services.
