About
Hi, I'm 杨毓恺 and I go by Sebastian. I build 3D applications that move software beyond screens and context-aware agents that turn perception into action.
I'm a senior AR/VR Software Engineer at Apple working on Siri and Vision Pro. Prior to this, I was an engineer at Meta Reality Labs focusing on VR applications.
Before Meta, I graduated from Carnegie Mellon University with dual degrees in Statistics and Machine Learning + Information Systems, along with minors in Business Administration + Game Design.
Thank you for taking the time to visit my website! If you'd like a quick overview of my work, please check out my resume.
Feel free to look around. : )

I focus on AR/VR × AI/ML because I believe the next era of software will be spatial, contextual, and agentic.
- Spatial: Interfaces will move beyond 2D screens and expand into immersive, embodied experiences.
- Contextual: Our surroundings — voices, people, objects, and surfaces — will become part of the input. Software will sense the situation, infer intent, and respond fluidly as part of the environment.
- Agentic: Instead of waiting for commands, applications will grow into active partners—noticing patterns, reasoning alongside us, and taking initiative while remaining transparent and trustworthy.
The best way to predict the future is to build it together. If you’re exploring this space, I’m happy to connect.
Let’s have an adventure!
