Hi, I'm Harry Sui 👋

Senior Front-end Engineer (7+ years) based in Tokyo 🇯🇵, building practical products at the intersection of AI, language learning, and developer tools.

I specialize in scaling front-end systems, modernizing legacy platforms, and shipping tools people actually use daily.

TypeScript JavaScript React Vue.js NodeJS Micro-frontends Kubernetes Docker CI/CD

🚀 What I’m building

  • 📚 Language learning tools with practical daily use (not demo-ware)
  • 🧩 Chrome extensions for instant context, vocabulary, and reading support
  • 🤖 AI-assisted workflows for transcripts, grammar explanation, and review systems
  • ⚡ Small products that prioritize speed, clarity, and real outcomes

🤖 AI Interests

I’m deeply interested in applied AI — especially using LLMs to improve real workflows, not just demos.

Current focus areas:

  • 🔍 RAG-based learning/support experiences
  • 📝 Prompt design and evaluation loops
  • 🧙‍♂️ Lightweight AI agents for language learning and productivity
  • 🧪 Turning small AI experiments into daily-use products

🔥 Featured Projects

🌍 Languages

  • 🇨🇳 Mandarin (Native)
  • 🇺🇸 English (Professional working proficiency, CEFR B2)
  • 🇯🇵 Japanese (JLPT N2, pursuing N1)

🎯 Current Focus

  • 🎌 Learning Japanese
  • 🏗️ Building tiny tools that compound over time
  • 🔬 Going deeper on applied AI engineering
