About

Professional summary

I am a Senior Manual QA Engineer with more than five years of experience delivering quality assurance for web, mobile, desktop, gaming, fintech, logistics, entertainment, travel, luxury fashion, and e-commerce products.

I specialize in finding high-impact defects that are often missed by standard test cases, including edge cases, broken user flows, usability issues, and cross-platform inconsistencies. I approach testing with a strong exploratory mindset and a focus on product quality.

My experience includes functional, regression, smoke, sanity, usability, localization, API, integration, accessibility, cross-browser, and cross-device testing. I also validate UI/UX implementations and provide clear, actionable defect documentation for development teams.

I have tested more than 28 client products for brands and platforms across multiple industries, often under tight delivery timelines. I am comfortable working independently, planning test coverage, prioritizing risks, and supporting go/no-go release decisions.

I use tools including Jira, TestRail, Trello, Postman, Charles Proxy, Fiddler, GitHub, and Playwright. I also have foundational Python knowledge and use Playwright for test automation when appropriate.
