What I'm looking for

I'm open to remote roles, independent contracting, EOR arrangements, and employer-sponsored relocation, where I can build high-performance real-time communications, media, SDK, systems, or Apple-platform products.

I've built and shipped Kyrifix Dictionary, Kyrifix Caption, and Kyrifix Practice across macOS, iOS, and watchOS, owning product definition, architecture, backend systems, App Store releases, and production maintenance.

At Shunwang Technology, I maintained cloud PC and cloud gaming SDKs spanning WebRTC/OWT, FFmpeg, Win32, IPC, permissions, and virtual printing. I improved 2K software encoding from approximately 15 fps to 30 fps and built a remote print-redirection system that passed internal testing with packet loss below 10%.

I enjoy breaking complex real-time media, P2P networking, and multi-process systems into reusable, high-performance modules. My work includes standalone ICE/STUN/TURN research, low-CPU real-time captioning, CloudKit synchronization, OCR lookup, and offline-first Apple applications.
