I'm a freelance engineer who builds custom "Kintone" apps and plugins using JavaScript. I also help with English-to-Japanese translation and editing, especially for tech-related content. With a solid understanding of engineering, I make sure my work is clear, accurate, and easy to follow. In addition, I am a certified calligraphy master (Shihan) with years of experience in traditional Japanese calligraphy. I create handwritten works on request, blending classical techniques with personal expression.
