Knowledge Trainer — Cross-Platform Quiz & Trivia Game

Knowledge Trainer is a cross-platform trivia and quiz game built in Unity, designed for casual play across mobile, automotive, and console platforms. The project required maintaining a single, scalable codebase while supporting very different input models, platform constraints, and certification requirements.

I worked on the project as a contract Unity developer via Upwork, with approximately five years of engagement overall, contributing to live product development, platform expansion, and long-term maintenance.
