I'm Nguyễn Trần Hoàng Long (Nguyen Tran Hoang Long), a developer from Vietnam 🇻🇳. I like the hard, low-level parts:
- making closed systems talk to open ones, like an OpenAI-compatible API in front of a web chat or a native Linux port of a desktop app;
- squeezing GPUs into virtual machines;
- shipping small, fast tools in Rust and TypeScript.

Research into running a macOS guest with GPU acceleration on Linux/KVM. The main track is a paravirtual GPU (virtio-gpu + Venus/Vulkan) rather than passthrough, and the goal is to generalise it across hardware. Early research.
