Summary
🤩
Rockstar🎓
Top SchoolHenry Swanson is a software engineer with 12 years of experience building reliable back-end systems and tooling, now based in Redwood City and currently at Northwood after five years as a production/senior production engineer at Meta. He brings deep practical expertise in distributed systems and type-safe client libraries, demonstrated by contributions to LogDevice where he improved Python typing for C++ bindings and strengthened server- and client-side code. Comfortable across low-level systems and developer experience work, Henry pairs pragmatic engineering with a math-first mindset from his Caltech math/CS background and early research in antenna simulation and MRI visualization. He has a taste for elegant, experimental engineering—publishing fun Rust projects and occasional math writing on GitHub—and a history of turning prototypes into durable tools, as he did at Pure Storage. Colleagues would describe him as meticulous about correctness and types, with an enduring curiosity that shows up in sentimental preservation of early projects.
