About
I've run my own business, so I know how to think at a business perspective. I know tech, so I can build things on my own. I majored in design, so I'm skilled at creating UI as well. I especially focused on UX, so I can also research users. I communicate well with clients. I would find a way to make it work, no matter what. I get along well with people.
