My Journey

I'm a builder at heart, driven by one core principle: transforming complex challenges into elegant, impactful solutions. My journey started with mastering the full stack—React, Next.js, and Node.js—but my curiosity has always pulled me toward the next frontier: AI Engineering.

What I Do

Currently, I focus on building intelligent applications with Large Language Models, using tools like LangChain and Python to create practical, AI-powered features. I also love sharing knowledge through technical writing—documenting everything from React patterns to agentic coding with Claude Code.
