Hi, my name is

BO HE

Machine Learning Engineer · AI Applications

I'm a software engineer and CS master's student at Northeastern University in Seattle, focused on building reliable, scalable systems end to end. My work spans high-concurrency backend services, ML-powered products, and Extended Reality (XR), and I enjoy turning ambiguous problems into clean architectures that hold up in production.

About

I gravitate toward the parts of software that decide whether a product holds up — clean data models, well-drawn service boundaries, performance, and the tests that keep it honest. I like going deep on a problem, shipping something real, then sharpening it. Right now I'm splitting my time across backend systems, applied machine learning, and Extended Reality — I enjoy building where the platform is still being figured out. If any of that resonates, I'd love to connect.
