What I'm looking for

I'm open to remote opportunities, full-time or part-time.

At EVO, I own release quality for mobile products and built and maintain an automation framework using Kotlin, Appium, Maestro, Espresso, and XCUITest. It provides 76% stable regression coverage, and I integrated automated checks into the GitLab CI release pipeline, reducing critical defect leakage to production by 40%.

I test payment flows end to end, including provider integrations, webhooks, refunds, and balance rules. I also use Claude and custom LLM scripts for log triage and flaky-test detection, and mentor manual QA engineers through code reviews and workshops.
