Ting-Jui Hsu
I love to build products while exploring the frontier of computing.
I previously worked as a software engineer at Klarna, a payment company, where we develop and maintain the merchant portal. I also love building applications to interact with people. Therefore, I later started a clinical note-taking service that boost medical workers' productivity after leaving Klarna.
