I'm a Senior Unity / XR Engineer and Technical Lead focused on software architecture, gameplay systems, cross-platform development, and interactive experiences.

I have experience delivering commercial projects across Nintendo Switch, XR, Windows, iOS, and Android, from requirements analysis and system design to implementation, optimization, and release.

• Architecture serves the product
  I design around real product needs and expected change, introducing abstraction only where it creates practical value.

• Clear domain and responsibilities
  I establish shared terminology and clear ownership before implementation so systems are easier to communicate, maintain, and extend.

• Design for change
  I keep gameplay, networking, platform-specific code, and presentation behind clear boundaries so each part can evolve independently.

• Specification-driven, agent-assisted development
  I define behavior and acceptance criteria before implementation, then use AI agents to accelerate execution while keeping verification and review explicit.
