What I worked on

  • Maintained 50+ live Unity mobile titles, improving UI/UX and core gameplay stability across deployments
  • Upgraded SDKs and platform modules to keep titles compliant with evolving app-store requirements
  • Resolved 100+ QA-report bugs by modifying Unity prefabs and C# scripts

Note

The titles I worked on are live on the App Store and Google Play, and I'm happy to point you to the specific games and fixes on request.
