What I'm looking for

I’m looking for a game studio where I can own gameplay QA end-to-end—planning tests, validating builds, and improving defect reporting—while collaborating closely with design and engineering to ship stable, polished Unity experiences.

I’m a Gameplay Tester with 2 years of hands-on manual testing experience on Unity based projects. I specialize in testing core gameplay mechanics—identifying edge cases, soft-locks, progression blockers—and performing regression testing across multiple builds, including 40+ builds. As the sole QA on a Metroidvania/Platformer project, I owned the full defect lifecycle end-to-end using Jira and Azure DevOps.

I also bridge design and development to validate that gameplay systems match both creative intent and technical constraints. I created detailed test plans for an unannounced Deck-Building project, covering RNG systems, Save/Load integrity, performance, and UI/UX consistency, and I completed regression on a mobile football project in a production environment. Comfortable with Git-based workflows, I conduct pre-deployment testing and branch-based validation for newly developed features.
