EXPERIENCE

Wayfair, Boston MA — Data Scientist Intern

August 2019 – December 2019

  • Improved and standardized current Geo A/B testing methods by moving parts written in R into Python and introducing parallel computing for shortening the test design time from more than 20 hours to 2 hours.
  • Expanded Geo A/B testing method to new markets. The improved method reduced variance on new markets (30% revenue compared to mature US market) by more than 40%. Currently being used in Canada.
  • Created a map-based visualization tool for presenting A/B testing test design. Using the tool, engineers and scientists can communicate more easily and efficiently with PMs and stakeholders for discussing test design as previously only a list of area IDs were shown.

Featurespace, Atlanta GA — Data Scientist Intern

May 2019 – August 2019

  • Processed the real-world streaming financial dataset and engineered 20 new features for identifying users and merchants’ behaviors.
  • Researched more than 15 papers on interpretable machine learning.
  • Integrated several methods including ML techniques and built a model-agnostic interpretable machine learning model. Interpreter achieves 99% accuracy for the local boundary and >80% for the global (evaluation metrics introduced in LIME paper).

Overlay Technology, Singapore — Software Engineer Intern

June 2017 – July 2017

  • Compared different libraries/existing methods for AR by implementing and embedding those into the company's Android app.

PROJECTS

Google Ignite CS at Emory leader for coaching high school students Arduino

Initiated first Ignite CS team at Emory founded by Google for coaching high school students programming knowledge. Leader of a team of 8 mentors for mentoring 16 mentees. Designed the course using Arduino for fun learning and guided mentees throughout the process.

Chest X-Ray Diagnosis X-ray diagnosis by Deep Learning
