What I'm looking for

I’m looking for a team where I can iterate gameplay fast, work closely with artists and designers, and ship polished Unity experiences—especially mechanics/tech design and AR/virtual features.

I’m a Gameplay/Tech Designer who builds and refines core game mechanics in Unity, focused on smooth controls, balanced gameplay, and maintainable systems. In my current role, I’ve developed modular gameplay features (ball physics, shooting, power-ups) using efficient C# code and iterated quickly through playtesting.

I partner closely with artists and designers to integrate assets and ensure a cohesive player experience. I also profile and refactor scripts to optimize performance, achieving stable framerates across platforms while keeping iteration fast and reliable.

Earlier, I managed and designed an AR product in Unity, including a virtual karaoke background that boosted immersion. I’ve also contributed to multiple prototypes and pitched ideas to my club, designing levels and helping create intuitive gameplay with clear, readable documentation.
