What I'm looking for

I want to build and ship AI-driven VR on Meta Quest as a hands-on Unity engineer—owning end-to-end code, optimizing real-time performance, and collaborating closely with backend/AI and product to deliver impactful healthcare experiences.

I’m a Unity / C# engineer shipping real-time interactive experiences on Meta Quest, and I’ve owned full client code bases end to end as the sole engineer on AI-driven VR products. Since Dec 2025, I’ve been the sole client engineer on an AI VR Avatar, delivering real-time conversational AI characters in VR by owning the Unity / C# code base and optimizing performance while working closely with backend/AI and product.

Before that, I shipped Meta Quest 2/3 virtual labs and healthcare-focused VR apps through my Unity / VR Developer work, including CircutexVR and Fashion.ED, plus an AI Calm Room app and a computer-vision Pain Mapping tool with healthcare partners. I also led a multidisciplinary student engineering group as Coordinator, combining delivery with mentoring and external funding/partnerships—while staying grounded in Agile practices like Scrum, Git, code review, and CI/CD.
