San Francisco, California, United States
Hey! I'm Justin and I'm a full-stack software engineer at Cotiviti where I create enterprise software to help save healthcare patients millions every year. In the past, I interned at Sermonis.ai as a machine learning engineer where I trained and developed intelligent virtual assistants for commercial and industrial purposes, as well as at the University of California, San Francisco as a frontend web developer and a software QA tester for the IndustryDocumentsLibrary and the Illios Project. Besides computer science, some passions of mine are street photography and linguistics; as such, I can speak English, Cantonese, French, German, and beginner-level Italian. Feel free to message me if you have any questions about my experience or have any opportunities for me!
