About
Seven years of shipping systems that have to stay up.
I work on the compromised account detection service behind Microsoft Entra ID — the pipeline that decides whether your credentials showed up in a breach. Before that, search and recommendation infrastructure at CareerBuilder, and a restaurant SaaS platform at qMenu. I like the parts of the job where correctness and throughput fight each other.
Guangzheng Wu
Software Engineer II · Microsoft
I started out building mobile apps and hackathon hardware, wrote a master’s dissertation on neural networks for depression diagnosis, then spent the last seven years on the backend: graph databases and vector search at CareerBuilder, and now multi-region .NET services on Azure that process 50 million security signals a day. I still build things on the weekend — a stack of apps in progress, and a quadruped robot that is slowly learning to walk.
