Mathematics & HPC
Stony Brook Ph.D. and Los Alamos research: numerical methods, computational geometry, and parallel algorithms.
Engineer at Meta
I make machine intelligence dependable.
I’m Duo Wang, an engineer with an applied-math foundation. I work across GPU training, real-time ads serving, data infrastructure, and payments.
01 / Trajectory
A career shaped by the hardest constraint.
The domain has changed—from computational geometry to real-time systems, data platforms, payments, and AI infrastructure. The thread is constant: understand the constraint and improve the system around it.
Real-time systems
AppNexus and Manage.com: bidding algorithms, rare-event ML, and low-latency systems under live traffic.
ML & data platforms
Netflix and Opendoor: experimentation, optimization, serving abstractions, and shared compute infrastructure.
Global systems
Stripe: routing and cost-efficiency strategy across large-scale payment infrastructure.
AI infrastructure
