Zeeshan Mustafa — Freelance QA Automation Engineer | Playwright · Selenium

About Me

Engineering quality,
end to end

Zeeshan Mustafa is a freelance QA Automation Engineer based in Karachi, Pakistan, currently working at Folio3 — a US-based enterprise software company — where he builds cross-platform E2E test automation for CXApp across Web, iOS, and Android. With hands-on experience in Playwright (TypeScript & Python), XCUITest (Swift), and Appium (Java), he designs frameworks on the Page Object Model with full CI/CD integration via GitHub Actions. At Vidizmo AI he maintained an 89% CI/CD pass rate across Playwright suites; at The ModVentures he cut manual testing effort by 75% through Appium automation. As a freelance QA automation engineer available for remote engagements worldwide, he builds AI-accelerated test frameworks using Claude Code and Playwright MCP. You'll find his technical guides on Medium and open-source projects on GitHub as ZeeshanMustafaJumabhoy.

My approach goes beyond test counts — I focus on pipeline stability, meaningful coverage, and reducing noise so engineering teams can ship with confidence. I actively investigate CI failures, triage flaky tests, and contribute to acceptance criteria alongside developers.

Outside core QA work, I explore AI-assisted test automation: publishing technical guides on Medium, open-sourcing Claude Code skill frameworks, and integrating AI tools into real QA workflows. I write things I wish existed when I was starting out.

Your team ships features.
Bugs shouldn't ship with them.

Most teams treat QA as a checkbox — until a bug reaches production. I build automation frameworks that actually prevent that: using plain-language requirements → runnable Playwright specs, AI-assisted test generation via Claude, and CI pipelines that catch regressions before a human even looks at them.

3× more test cases per sprint — same engineer, Claude writes the boilerplate

~2h to author a full test suite that used to take 3 sprint days manually
