What I'm looking for

I'm looking to apply my QA and audio-quality awareness to precise testing, annotation, and review work where consistency, clear feedback, and detecting subtle issues matter.

I've tested PC, multiplayer, mobile, console, and enterprise software across Magic Media Studio, QLOC, SimCorp, Huuuge Games, and Testronic Labs.

At Magic Media Studio, I execute functional, regression, exploratory, system, smoke, and release testing for PC and multiplayer titles. I design test plans for gameplay, UI/UX, backend features, and integrations, then document defects in Jira with reproduction steps and impact analysis.

I've validated financial-software workflows, business logic, APIs, and backend data using Postman and SQL, while supporting UAT and release validation. Across game projects, I’ve verified localization, LiveOps events, production deployments, compatibility, stability, and performance.

I bring strong pattern recognition and critical listening developed through guitar practice, helping me spot subtle inconsistencies including noise, clipping, distortion, and timing issues. I value precise documentation, consistent review standards, and clear feedback that helps teams improve product quality.
