Software engineer from Taiwan, based in Japan.
4+ years across backend systems, web applications, internal tooling, and AI-assisted product development.
- AI agent infrastructure — agent rules, dispatch workflows, and prompt tooling to accelerate the full dev cycle (planning → implementation → review)
- Backend services & developer tooling — Go, Java, PostgreSQL, Docker across production systems
- JapanJob — a job matching platform for Chinese-speaking job seekers in Japan (Go · React Native · PostgreSQL · Redis · Docker)
- Multilingual products — systems designed for users operating across Taiwan and Japan
Most of my active development is AI-assisted —
I use Claude Code with custom agent workflows as a core part of the process.
- Tyoho Group: end-to-end product development — Java, Go, React, React Native, PostgreSQL, Redis, Docker, GitHub Actions
- HP Inc. / vCosmos: full-stack in a Scrum team, cloud-based testing infrastructure
- K-JUMP Health: backend and real-time data processing for a health data platform
Reusable agent rules, subagents, and workflow structure for AI-assisted software delivery.
Personal Claude Code config — PM agent, codex-executor, reviewers, slash commands, dispatch scripts.
Language-agnostic QA rules for AI coding agents — structured docstrings, mutation self-checks, explicit test-layer decisions. Designed for @import into CLAUDE.md / AGENTS.md.
LAN file sharing service — Go, Nginx, Docker. Low memory usage, simple upload/download.
