About Me

🎓 Who Am I?

I'm a 14-year-old coder from Vietnam with an insatiable passion for building things. Since I discovered programming, I've immersed myself in everything from map platforms to reverse engineering and backend automation. My journey is driven by curiosity, persistence, and a love for solving problems through code.

💪 What I Do

I specialize in full-stack web development, reverse engineering HTTP requests, and automation workflows such as homework/task helpers. I also learn Arduino and electronics projects while continuing competitive programming and advanced tooling. Every build is a chance to improve speed, reliability, and impact.

🚀 My Philosophy

Code is art. Every project teaches me something new. I believe in writing clean, efficient code and building applications that matter. Whether it's automating task flows, reverse engineering APIs, or building map systems, I approach every challenge with creativity and technical excellence.
