Hi, I'm Kang Hangoo 👋

📍 Korea | 🛠️ Backend/Data Builder | 📚 Learning in Public

Aspiring binary magician.

I believe in the compound power of experience.

I don't stop at just using tools — I dig into how they work under the hood, make that knowledge my own, and enjoy expressing it through code and writing.

Java Kotlin Python TypeScript Web

Current Projects

  • Building trading infrastructure, a search engine, and frameworks from scratch through cluefin, cluefin-dure, crescent, and summer-sandal — validating core internals hands-on and documenting what I learn along the way.

Open Source

  • cluefin - Python-based financial toolkit for Korean market analysis and trading automation
  • cluefin-dure - TypeScript trading platform that unifies Korean Investment Securities APIs into a single interface
  • crescent - Java-based search server built on Lucene + Spring Boot for learning and experimentation
  • summer-sandal - Personal framework project reimplementing Spring Boot concepts in Kotlin to understand its internals
