Joined Nov 2026

Senior QA Engineer with 5+ years of experience delivering quality for mobile (Android/iOS, Unity), mobile product teams, web, and desktop products across GameDev and E-commerce.

I own feature and release quality end-to-end: requirements clarification, risk-based test strategy, regression planning, release readiness and post-release monitoring with analytics.

I use ChatGPT, Claude and Gemini to accelerate test design, documentation, release notes and log/incident analysis, while keeping final decisions and validation in manual QA.

I work closely with developers, product, support and analytics teams, and help structure testing processes and documentation for the team.
