Senior QA Engineer specializing in mobile/web automation and AI-assisted QA workflows for global products.
What I'm looking for
I’m a Senior QA Engineer with 6+ years of experience in manual and automation testing for mobile and web applications, recognized as “Engineer of the Year - QA 2024” at Grid Dynamics. I currently own QA for the full suite of 5 Williams Sonoma brands, maintaining 370+ automated test cases using Appium + Selenide (Java) on iOS.
In my work, I combine real-device validation (BrowserStack), deep network and API debugging (Proxyman), and reliable CI/CD execution (Jenkins) to protect critical flows like Apple Pay and checkout across brand apps. I also design AI-powered QA agents with GitHub Copilot—automating bug creation, UI inspection (Figma vs. live), and PR review validation against Jira acceptance criteria.
Previously, I tested native iOS and Android applications for Audi’s mobility and fleet platforms, running sanity, functional, and regression suites using Waldo and TestRail. Before that, as the sole QA engineer at Perfomatix Solutions, I owned end-to-end quality across healthcare, logistics, oil & gas, and sports, mentored junior engineers, and translated requirements into solid test strategies in Agile teams.
