Computational foundations
Numerical methods, computational geometry, and parallel algorithms.
Engineer at Meta
I make machine intelligence dependable.
I’m Duo Wang, an engineer with a math education. I work across large-scale training, real-time serving, data infrastructure, and distributed systems.
01 / Trajectory
A career shaped by the hardest constraint.
Real-time systems
Algorithms, rare-event ML, and low-latency serving under live traffic.
ML & data platforms
Model optimization, experimentation, shared data platforms, serving abstractions, and routing systems.
AI infrastructure
Efficient, reliable training systems at scale.
