👋 Hi, I'm Krit — a Developer passionate about IoT, Automation, and Japan 🇯🇵

I'm a self-taught software developer from Thailand.
I love solving real-world problems with code — from backend systems and IoT to web automation and language learning apps.
Right now, I'm studying Japanese with the goal of living and working in Japan someday.

🗾 Why Japan?

I’ve always admired Japan’s technology, design, and discipline.
I’m currently learning Japanese, with the goal of living and working there — especially in IoT, automation, or backend systems.

I’m also building apps to help others learn languages too — because learning should be fun, interactive, and visual.
