Summary

Rockstar🎓
Top SchoolCharles Hu is a Foundation Software Engineer based in San Francisco with 10 years of experience building polished iOS and web applications and a strong eye for UI design. Currently at Apple, he contributes to Swift’s core libraries—most notably adding AttributedString and bridging improvements in swift-corelibs-foundation—bringing low-level Swift expertise alongside front-end sensibilities. Previously he led front-end migrations at Delphix from AngularJS to Angular and from REST to GraphQL, and co-founded an iOS startup, demonstrating both product and engineering chops. Comfortable across full stack boundaries, he blends systems-level Swift work with practical web engineering optimizations like drastically reducing test/build times. He holds a CS degree from UW–Madison and keeps a habit of improving developer-facing foundations that quietly make apps more reliable and expressive.
