Labeling Experience

Image Classifier — Non-Destructive Identification System (end-to-end training/prediction workflow)

OtherImageClassification

Built an image-classification ML workflow where users upload training data and define regions of interest to train an ensemble model. Ran batch predictions through a browser interface and evaluated performance using leave-one-image-out cross-validation. Added interpretability visuals such as confusion matrices, PCA, and spectral plots to understand labeling/prediction quality. • Defined regions of interest for training inputs • Trained soft-voting ensemble (SVM, Random Forest, XGBoost) • Performed leave-one-image-out cross-validation • Produced interpretability visualizations for evaluation

Data Analyst, Graduate Research (ETL migration and validation)

Other

Performed ETL migration and validation to preserve dataset integrity during database transfer between systems, ensuring downstream analytics and ML-ready data quality. Wrote validation scripts to enforce data integrity constraints after moving an IMDB database from one storage model to another. Focused on correctness checks as part of the data preparation pipeline for later modeling and analysis work. • Migrated IMDB database across MongoDB and SQL • Authored data validation scripts • Ensured data integrity post-migration • Supported reliable downstream dataset usage
