About Me
Guanghao (Gary) Wei
I am a machine learning engineer and researcher who builds efficient, reliable systems for large-scale learning. My interests span machine learning systems, distributed systems, high-performance computing, and AI for science.
I earned an M.Eng. in Computer Science from Cornell University and dual B.S. degrees in Computer Science and Mathematics from UMass Amherst, where I also minored in Japanese.
Outside work, I enjoy building open-source tools, solving CTF challenges, making games, and playing soccer.
My ambition is to build something that genuinely matters. I am still learning—and still on my way.

My Skills
Machine Learning Systems
I build and contribute to machine learning systems with PyTorch, JAX, and related tools.
My work emphasizes efficiency, reliability, and real-world performance at scale.
Full-Stack & Cloud
I have built full-stack applications with Django, Express, SQL and NoSQL databases, and AWS serverless services since 2019.
This site is generated with Hugo and deployed to AWS through GitHub Actions.
Distributed Systems & HPC
My systems background includes distributed algorithms, fault tolerance, CUDA, Triton, OpenMP, and MPI.
I have built projects ranging from Paxos and Raft to multi-GPU scientific computing. See my academic profile for publications and research projects.
Game Development
I learned game development with Unity in UMass CS 576 and built several small games.
I enjoy games both as a player and as a developer.
Cybersecurity
I studied reverse engineering and vulnerability analysis at UMass Amherst and continue to practice binary analysis and exploitation through CTFs.Get in Touch
