I’m a developer passionate about functional programming, JavaScript/TypeScript, and open-source. I enjoy solving problems, building tools and libraries, and contributing to developer communities.

• Build open-source libraries and tools, especially in JS/TS ecosystem
• Maintain and contribute to translation/localization efforts (e.g., React documentation)
• Share articles, thoughts, and code on developer topics
• Collaborate with teams, mentor others, and drive best practices

Here are a few of my public repositories you might find interesting:

• Functional programming (FP) & TypeScript
• JavaScript/Node.js libraries & tooling
• Web & frontend ecosystems (React, etc.)
• Open-source community, localization & documentation
• Developer experience (DX), code clarity, maintainable architecture
