About

Hello, I’m Beom-ku Jung, a software developer with 8 years of experience.

During my military service, I worked as a system operations officer and developed a PHP-based unit homepage and a barbershop reservation system.
I started coding through self-study on my smartphone, and as I solved problems, I became fascinated with programming.

After completing a government-supported Java training program, I began my career at a startup, gaining hands-on experience.
Currently, I primarily work with TypeScript, focusing on improving developer experience through type inference and test automation.

Projects

@imhonglu/new-wheels

This project started with the idea of “creating a type-safe library that fits my preferences.”
The goal is to minimize unnecessary dependencies and maintain high test coverage while
leveraging TypeScript’s type system to design safe and intuitive libraries.

Currently, I am developing the following libraries:

  • @imhonglu/json-schema
    A JSON Schema 2020-12 Draft-compliant implementation, validated with the JSON-Schema-test-suite.
    Supports schema-based static type inference, enabling a declarative approach to defining safe data structures.
  • @imhonglu/format
    A strongly typed string formatting library compliant with RFC standards.
    Provides an API similar to the native JSON API for intuitive usability.
  • @imhonglu/pattern-builder
    A RegExp builder that simplifies complex regular expressions.
    Enhances readability and makes maintenance easier.
  • @imhonglu/toolkit
    A collection of commonly used utility functions and types to streamline development.
    Reduces repetitive code and maintains consistent patterns in TypeScript projects.
  • @imhonglu/type-guard
    A type guard library inspired by Jest matchers, providing a chainable API.
    Uses a Proxy-based implementation to minimize overhead while ensuring strong type safety.
  • @imhonglu/type-object
    A type-safe wrapper for Object APIs that closely aligns with native behavior.
    Enhances safety when working with Object.keys, entries, fromEntries, hasOwn, and similar APIs in TypeScript.
