QA Engineer at Hub88 who raised Playwright regression coverage by 40% and cut manual regression effort by 30%.

At Hub88, I investigate authentication, role-based access, and payment workflows across web applications and APIs. I use log analysis and API tracing to investigate production incidents and work with developers to identify root causes.

I developed and maintained Playwright automation in CI pipelines, increasing regression coverage by 40% and reducing manual regression effort by 30%. Across fintech, payment, and iGaming platforms, I validate APIs with Postman, check data with SQL, and use Claude Code and GitHub Copilot in my testing work, verifying their output.
