Hey, I'm Thiyagu β a full-stack engineer based in Tokyo with 3.5+ years of experience building production web applications. By day I ship features in Vue 3, TypeScript, Java Spring Boot, and PostgreSQL β working daily in both Japanese and English (JLPT N2 in progress).
Outside work, I run KitsuneChaos β an experimental platform where I build:
- β‘ Physics & electronics simulations
- π§ AI-assisted developer tooling
- π¨ Creative workflow systems
- π§ͺ Browser-based experiments
My background is an MSc in Physics, and my work sits at the intersection of:
TypeScript Γ Physics Γ AI Γ Interactive Learning- Shipping full-stack features on a production management platform (Vue 3 / Spring Boot)
- Expanding KitsuneChaos simulations & tools β modern learning experiences inspired by PhET
- Exploring AI-native interfaces & agent systems
- JLPT N2 β deepening my Japanese for long-term engineering growth in Japan
- Performance optimization, AWS & distributed systems| Project | Description | Stack | Status |
|---|---|---|---|
| π¦ KitsuneChaos | Interactive tools, simulations, and experimental web experiences | Angular TypeScript Node.js |

I write regularly β fiction and tech:
- π©Έ Blood Trails β a noir thriller serialized weekly on Royal Road
- π¦ Kitsune Chaos β a Substack newsletter on noir fiction, tech & science
βΈ AI-native interfaces & agent architectures
βΈ Physics visualization systems
βΈ Browser rendering performance
βΈ AWS system design
βΈ Human-centered learning tools
βΈ The Japanese tech ecosystemGood tools teach.
Great tools make people curious.
