Hi, I’m Yuta Kobayashi.
I was born in 2008 and currently live in Japan. I have been interested in the intersection of technology and society since a young age. My interests include accessibility, privacy, public systems, and more. To share my journey and insights, I maintain a monthly blog where I reflect on my experiences and learnings. You can explore these posts at /blog, and find my favorite links and resources at /favorite. Additionally, I share my personal digital garden at notes.yutakobayashi.com, where I document my thoughts, learnings, and explorations in a more interconnected way.
I started coding when I was 7 years old and have mainly worked on blogs, web projects, and machine learning projects.Recently, in my personal projects, I’ve been focusing on hardware and have been creating IoT machines using M5 Stack and Arduino.
Work Experience
I started working as a freelancer when I was 14 years old, mainly focusing on web development and design.
