Summary
🤩
Rockstar🎓
Top SchoolJay Herron is a Head of Cloud Software based in Salt Lake City with eight years of experience building high-performance, server-side Swift backends and cloud infrastructure. He leads a team of engineers at PassiveLogic, drove a backend performance increase from 100 to 10,000 concurrent users, and instituted company-wide release, monitoring, and on-call practices. Jay architected a GraphQL API for building data that unifies diverse domains (architectural, equipment, historical) and optimized an in-house ORM for 30x faster queries while championing TimescaleDB for time-series needs. A long-time open-source contributor, he has improved core Swift projects like Vapor and GraphQLSwift—adding features, fixing subtle encoding/decoding bugs, and enhancing middleware and tracing. With a B.S. in Mathematics and a background in energy efficiency analytics, he blends quantitative rigor with pragmatic product engineering to solve complex building and cloud problems. Colleagues describe him as a curious builder who writes “small-batch, grass-fed” code—thoughtful, well-crafted, and production-ready.
