About Me


Hi I am Yvette Zhang :wave:!

I have a tri-color corgi named Happy ♋, and I used his picture on the front page. I love making Chinese cuisines 🥟, walking my dog and letting him say hi for me 🦮, and creating all kinds of handcrafts 🧩.

I also spend quite some money each month to take online courses, and I know I’ll become a data scientist one day! 🎉

Analyst, DIA Associates

2019.04 — present

I built a pipeline from data integration and cleaning to model selection and evaluation to predict debtors’ repay possibility and conditional liquidation rate for an internal project. In the daily work supporting my client at American Express, I wrote SQL queries on a daily basis to extract data, perform analyses and create reports. I also automated multiple report-generating processes by writing Python scripts, which greatly reduce the monthly manual efforts.

Graduate Student, Columbia University

2017.09 — 2019.02

I took Python and Analytics in Practice, and I built up my Python programming skills through the coursework and hands-on experience with real-world data. In Simulation and Deep Learning courses, I further honed my programming skills by designing queueing algorithms and training Neural Network models in Python. I was a TA for Columbia online course Analytics in Python (EdX course), helping write grading codes for assignments and holding virtual Q&A sessions to answer students’ questions about coursework.
