Software engineer based in Tokyo. I work on and enjoy Apple platform development, developer tooling, and build workflows.

Swift / Objective-C / C++ / Rust / Python / Bazel / CI/CD / Developer Tooling / AI-assisted Development

• exVMs (2026) - a Rust CLI and SwiftUI macOS app for exporting local Voice Memos recordings.
• FragSeal (since 2023) - a Swift/C++ CLI for secure, chunked backups.
• MetallicImage (2020) - an older Apple-platform image processing project. Mostly quiet now, but not necessarily gone forever.

• I work comfortably in Mandarin, English, and Japanese.
• You can reach me by mail, Telegram, or Twitter DM.
