About

Professional summary

I am a QA Automation Engineer and SDET with more than three years of experience designing and maintaining scalable automation frameworks for web and mobile applications.

I specialize in Playwright, Selenium, Cypress, and Appium, using Python and TypeScript to automate end-to-end workflows, improve regression coverage, and increase release reliability.

I have experience validating APIs, performing SQL backend and database checks, and integrating automated test suites into CI/CD pipelines. I focus on reliable test architecture, reusable utilities, and maintainable Page Object Model implementations.

I work closely with developers and product teams in Agile and Scrum environments to identify root causes, validate business rules, and improve software quality throughout sprint cycles.

I have managed test plans, defect tracking, and reporting with Azure DevOps and Jira. My background also includes Node.js, JavaScript, TypeScript, REST API integration, and full-stack environments, which strengthens my automation design and debugging capabilities.
