Xuan-Huy Cao

Senior Rust engineer with 6 years building low-latency, backend systems from the ground up. I help teams design and ship performance-critical infrastructure: backend services, real-time data pipelines, distributed systems, and trading infrastructure that has to be fast, correct, and reliable under load.

I work across the full backend stack. As founding engineer at a trading firm, I built market data ingestion services, order-execution gateways, order book servers, and a DSL compiler turning natural-language strategies into optimized Rust.

Before that I built embedded and signal-processing systems in C and C++, and a digital-twin simulation engine for large electrical grids.

Rust is my primary language, but I'm pragmatic. C++, Python, or TypeScript, whatever the problem needs. I have strong mathematical foundations (silver medalist at the national Mathematics Olympiad), which shows up in the work: graph theory, formal verification, and provably correct system design.
