# Cheng-Yu Pai > Data Science Backend Engineer Location: San Mateo, California, United States Profile: https://flows.cv/chengyupai I am a highly experienced Software Engineer with a background in both backend engineering and data science. Currently am working primarily to support a data science team by designing Snowflake data warehouses, ETL pipelines, and model deployment systems. My philosophy in data science/ML support is that the data scientists or statisticians should not have to worry about solving Software Engineering problems. By making it easy to do local development and standardizing model deployments, data science teams can iterate quickly to changing product requirements. I am a huge Linux fan and run Arch Linux on my primary computers, and am an advocate for Open Source. ## Work Experience ### Backend Software Engineer @ Bleacher Report Jan 2019 – Present Backend engineer at Bleacher Report, primarily supporting the data science team in doing data engineering, data warehousing, and model APIs. ### Backend Software Engineer @ Fandango Jan 2016 – Jan 2019 ### Software Engineer @ FactSet Jan 2015 – Jan 2016 ### Engineering Intern @ Flixster Jan 2014 – Jan 2014 Developed a highly accurate, user preference-tailored movie recommendation system for rottentomatoes.com using Hadoop and Mahout with the well-known ALS-WR algorithm running on Amazon EMR.
