I'm Masahito (most people call me Masa). I'm a web developer based in Amsterdam.

After leaving Central Saint Martins with First Class Honours, I freelanced as an Illustrator, taking part in exhibitions and working with clients in the UK, Japan and United States. While experimenting with animation, my interest shifted to interactivity and coding, which lead me to web development.




I'm fluent in English and Japanese. I started learning Dutch (Ik spreek nederlands een beetje).


I also code for pleasure, combining my pixel drawings and JavaScript to create experimental project, which I periodically share on CodePen: codepen.io/ma5a

My wife's hugs and my daughter's squishy cheeks keep me going.
