About

Hello there! I'm Carlos, a former Apple intern who spent two summers working on the Vision Pro's audio team (think Spatial Audio). I'm passionate about algorithms, app development, audio engineering, and spatial computing. Basically, if it involves making computers do cool things, I'm interested.

I currently work as a Research Assistant exploring LLM-Human Computer Interaction, generating synthetic expert corpus data, and building full-stack mobile and web applications across iOS, Android, and the web. Before that, I worked at Specify Collections Consortium developing and testing features for their Python/TypeScript SaaS platform running on AWS with Docker, your standard industry tech stack.

I won Apple's WWDC23 Swift Student Challenge and have spoken at international conferences in Japan, Korea, and the US. I write technical articles on Swift, Computer Vision, LLMs, Graphics, and Audio Engineering that have reached 25K+ views. Currently building Reze, a macOS job search assistant using on-device AI.

3D Graphics Rendering Pipeline(s) And Tutorials

Designed and developed a 3D rendering pipeline using C++, OpenGL, Swift, Metal, and MSL featuring dynamic lighting and instanced rendering. Then used those skills to create a series of articles on building a similar pipeline with Swift and Metal. Implemented interactive camera modes (default, tracking, ground) and split screen with user control via keyboard.
