Upgrade Unity Project with Tracking (+Cognitive3D SDK)

Unity Project Upgrade + Behavioral Data Logging + Cognitive3D Integration.

Description:
Seeking an experienced Unity developer to assist with a research project involving VR-based training. The tasks include:
1. Upgrade an existing Unity project from 2018.3.6f1 to 2019.4.40f1 (this is a minimum version) to enable SDK compatibility.
2. Integrate the Cognitive3D SDK to track eye and interaction data using the Varjo XR-3 HMD.
3. Implement behavioral and performance data tracking via Unity C# scripts, storing results in CSV format per user.

Specific behavioral and performance variables will be provided. Likewise, a detailed list of eye-tracking metrics and AOIs to be captured via Cognitive3D will be shared after onboarding.

Requirements:
- Proven experience upgrading Unity projects across versions.
- Familiarity with Cognitive3D SDK.
- Strong skills in Unity XR, C# scripting, and structured experiment data logging.
- Clean, modular code practices and ability to write developer-friendly documentation.

Deliverables:
- Fully upgraded Unity project (2019.4.40f1 or higher).
- Cognitive3D integration with defined AOIs and gaze metrics tracking.
- Behavioral and performance data logging implemented and saved as CSV.
- Brief developer documentation outlining data structure and logging flow.
