Top SchoolTongxi Liu is a software engineer at Amazon Payments with 10 years of experience building high-availability backend and full-stack systems that serve hundreds of millions of users. He blends production-grade cloud and systems engineering with academic expertise in computational linguistics and machine learning from UW and Columbia, having researched multilingual grammar engineering and automated grammar generation.
