About

Senior QA Engineer with 10+ years of experience delivering and scaling quality practices for Web, iOS, and Android products. I focus on automation-first quality engineering, helping teams ship frequently while maintaining confidence in release quality. My work centers on validating complex user flows across frontend interfaces, backend systems, and REST/GraphQL APIs. Automation & CI/CD: Hands-on experience building and improving automation using Cypress, Playwright, Selenium, and XCUITest, with an emphasis on stable, deterministic tests and CI/CD integration that produces fast, actionable feedback. Quality Ownership & Leadership: I own the full quality lifecycle—from automation planning and acceptance criteria to risk analysis and release readiness. I’ve led and mentored QA engineers while staying close to execution, strengthening regression strategies and improving defect workflows to reduce testing cycles (30%+ in previous roles). Business Impact: Much of my experience is in e-commerce and consumer products, where I’ve aligned testing strategies with product goals. I’ve supported initiatives that reduced customer drop-off by 50%, improved performance and stability, and increased conversion through reliable releases. I use AI-assisted tools pragmatically to speed up repetitive work and explore edge cases, while relying on engineering judgment and deterministic automation for final release decisions.
