My name is
Juntima Nawilaijaroen

First thing, I knew my name is too long. So, I go by Ja.


Yeah, a lot easier. Isn’t it?

I'm a UX designer specialised in automotive and mobile. But of course, open to a whole new world! 


I love to travel and connect to people with different cultures. I also love to learn new things! And if possible, pass it forward to the community by talking in podcasts and writing a blog.

I’m addicted to new technologies and gadgets. Totally in love with exploring new tools and finding a better design solution for my users.

My ultimate life goal is to conquer the world by designing a product ​that everyone would definitely use!
