PROFESSIONAL SUMMARY
Hands-on Senior QA Engineer with 20+ years of experience in game development across PC, console, and mobile
products. Strong background in end-to-end feature testing through the SDLC, client-server testing, test design, defect
investigation, release validation, and creation of practical QA documentation. Experienced with game engines, development
tools, version control, CI/build workflows, and cross-functional feature teams. I actively apply AI to QA work: requirements
decomposition, risk and edge-case discovery, structured test-case generation, test data/config analysis, and acceleration of
Python scripting and troubleshooting. Automation experience is strongest on PC/console projects with Python; mobile
testing is primarily manual on Android and iOS.
