Summary
👤
Senior🎓
Top SchoolKohei Hisakuni is a pragmatic software engineer with 11 years of experience building cloud-native systems and developer tooling, primarily in Go and JavaScript. He has shipped features and platform services at startups and scaleups—driving API improvements, performance optimizations, and migrations (Python→Go, VM/image pipelines) while improving team processes like on-call and incident response. At Ghost Security he integrated LLM agents and RAG to reduce SAST false positives and built a CLI for rapid prompt iteration, showing a knack for blending ML tooling with security use cases. He’s equally comfortable designing APIs with protobuf/Connect and digging into slow SQL queries or background workers to deliver sub-second UX. Based in Portland, he pairs a focus on practical, measurable improvements with a habit of obsessing over system and process quality.
