I'm Andrew Yong
I design and ship secure-by-default systems — post-quantum transport, hardened security tooling, and reliable infrastructure that stands up to real-world traffic.
Core toolkit
What I reach for when shipping ML features, securing systems, and keeping them fast.
Machine Learning
Production ML systems, from model training to deployment at scale
Cybersecurity
Offense-informed defense: threat modeling, hardening, and testing
Python Development
Fast, reliable services and data pipelines with modern Python
System Architecture
Designing resilient, observable systems with security baked in

Owner & Lead Developer · Updated November 2025
Post-quantum transport stack that replaces TLS + QUIC with hybrid X25519 + Kyber. Built in Rust for speed and safety.
