I am a math graduate from University of Cambridge and am currently pursuing a Master degree in Data Science at University of Sydney. I worked in ByteDance as a data analyst for a year. I am open to opportunities related to data science in all industries, with particular interests in tech and finance based on my previous experience.


• Provide 1-to-1 Python and Scratch tutoring to 5 students aged 6-18, and help them pass the Programming Level Tests;
• Tailor contents and approaches based on each individual’s interests and goals, deliver regular feedback for parents and students.

Project A: Human Labour Censorship Efficiency and Quality Control in Douyin(Chinese TikTok)
– Utilised Python to implement unsupervised machine learning techniques for setting sensible workplace productivity goals,
and boosting workplace effectiveness, which improved censors’ accuracy from 93 percent to 98 percent in 3 months.
– Collected and wrangled 1GB of censors’ actions data stored in Hive tables to set a standard for employees’ productivity by
K-means clustering, and analysed its rationality by visualisation.
– Monitored censors’ quality data based on different business metrics by creating and maintaining dashboards, and produced
daily and weekly quality reports to identify the latest problems.

Project B: Workforce Scheduling Analysis and Automation
– Allocated censors into 19 different daily work schedules to best fit the number of hourly incoming cases for review, which
minimised labour cost by 8 percent under the 15-min time lag constraint.
– Constructed a linear programming model that predicts daily time lags on labour distributions under various business needs
using Python, which allowed evaluation of the current scheduling.
– Achieved automated monthly scheduling using linear programming by arranging censors and dates in a table with business
requirements embedded into rows and columns constraints.
– Presented results to management team and wrote reports detailing algorithm and implementation to present to 4 other bases
