Work Experience
Machine Learning Engineer Intern
Coulomb Technology · Remote, USA
- Led end-to-end a tree-based regression pipeline using Python to be identified how material characteristics affect battery performance, increasing energy capacity from 100-120 to 135 mAh/g, saving over $1M in battery manufacturing costs.
AI Researcher
AIMA Research Institution · Remote, USA
- Conducted systematic literature reviews and co-authored research papers targeting Q1 journals and top-tier conferences; collaborated with institutional AI researchers to publish technical blogs.
- Designed and validated deep learning pipelines (ResNet34) for detecting mediastinal abnormalities on chest X-rays, applying advanced preprocessing techniques to improve diagnostic performance.
- Led extensive feature selection and model benchmarking studies, evaluating 10+ feature importance methods and 16+ ML/DL models (including ResNet variants, DiffMIC-v2, and 3D CNNs) for benign-malignant tumor classification; achieved AUC=0.903 and enabled radiologists to reduce diagnostic decision time by 50%.
Data Analyst Intern
CoxHealth · Missouri, USA
- Processed 11M+ physician unstructured text messages using SQL, PySpark, Pytorch and large language models (BERT) to extract radiology procedure requests.
- Analyzed modality demand-capacity trend by Time Series Analysis and visualized through Power BI dashboards to identify root causes of patient backlogs and revenue leakage, unlocking $1M+ in incremental revenue and reducing patient backlog by 50%.
- Developed a scalable ETL pipeline on Microsoft Fabric using PySpark and SQL to efficiently process 10TB+ of distributed HDFS data, reducing cloud computing costs by 40%.
Graduate Research Assistant
Missouri State University · Missouri, USA
- Led economic research on investment behavior of 200+ Gen Z and Millennial respondents using logistic regression (scikit-learn) and statistical analysis in R to inform financial literacy policy.
- Developed and deployed a scalable web application on AWS using EC2, S3, and RDS, resulting in a 30% increase in competition website traffic.
- Mentored 30+ students in Statistics, Python and R for data competitions, coaching machine learning model optimization that led to multiple hackathon awards.
Senior People Analyst
Home Credit B.C · Ho Chi Minh, Vietnam
- Developed gradient-boosting regression models to forecast employee tenure based on engagement and performance data, improving headcount planning accuracy by 80% and saving $100M in corporate staffing costs.
- Owned end-to-end hypothesis-driven A/B tests on recruitment websites and candidate communications that increased applicant volume by 20%, reduced attrition costs by 12%, and improved candidate Net Promoter Score (NPS) to +70.
- Extracted and analyzed Workday HR data using SQL to diagnose bottlenecks in the technical hiring process and workforce shortage.
