Work Experience

Data Scientist  •  Snapask Taiwan Limited

April 2022 - August 2022

・Collaborated with UX researchers to build a user persona and implemented customer segmentation via cluster analysis. Improved efficiency in the process of finding suitable interviewees and reduced probabilities of selection bias by providing a customer classification model.

・Developed tools and services such as modeling, dashboard automation, and business metric analysis to validate assumptions quickly and drive informed decision aids and recommend solutions, further improving the company’s enterprise product.

Software Engineer  •  ASM Pacific

May 2021 - April 2022

・Built a distributed data warehouse and ETL pipeline that can integrate big data from semiconductor equipment in real-time and provided a query system on a millisecond level.

・Developed statistical models to detect the outliers in manufacturing data by IQR and compared the differences in distribution between 2 datasets with EMD Algorithm.

AI Software Engineer  •  Wistron

April 2019 - April 2021

Provide AI solutions, design, develop algorithms, and deploy models involving fields such as computer vision, NLP, and knowledge graphs.

Research innovative and cutting-edge technologies that benefit the team’s project goals.

・Directed the development team to implement a complex natural language QA system based on the knowledge graph. I was responsible for ML algorithms part and made 3 presentations to share research results and insights. The participants included 77 individuals and 8 teams.
・Implemented an English-Chinese translation model using Transformer and leveraged the new model process by introducing techniques and results to the team.
