Work
-
2025.06 - 2025.08 Manufacturing Engineering Intern
New Hampshire Ball Bearings
- Reviewed and updated 300+ machine setup sheets for turning operations, incorporating current tooling, blueprint-based dimensions/tolerances, and material-specific parameters.
- Optimized feeds, speeds, and tool selections to improve production efficiency, reducing cycle times by 5%–30% per part while maintaining quality specifications.
- Collaborated with manufacturing engineers, line leads, and machine operators to resolve non-standard cases, validate changes, and standardize setup documentation across production lines.
-
2024.10 - 2025.01 Machine Learning Engineer
AI Student Collective
- Created an AI-powered e-commerce tool that generated optimized descriptions across 200+ products.
- Engineered text and price/meta features and solved severe class imbalance (900k rows; 12k positives) using hard-negative undersampling; validated with stratified splits.
- Built a Streamlit app for interactive inference with prompting, side-by-side diffs, and guardrails for factual and brand compliance.
-
2024.06 - 2024.08 Manufacturing Intern
New Hampshire Ball Bearings
- Authored 3 illustrated operator manuals for retainer-line machinery in 3 months, tripling historical documentation output.
- Collaborated directly with machine operators, line leads, and the manufacturing manager to capture tacit process knowledge and validate procedures.
- Standardized machine operation, tool change, and part-inspection workflows using visual documentation, reducing process variance and ambiguity on the production line.

SaleSense
Inference app and model pipeline for scoring product listings and generating improved descriptions.
- Optimized descriptions across 200+ products.
- Handled severe class imbalance (900k rows; 12k positives) with hard-negative undersampling.
- Streamlit interface with prompting, diffs, and compliance guardrails.
- 2024.10 - 2025.01
IntelliView
A real-time interview coaching tool that analyzes facial emotions and speaking dynamics to generate a feedback timeline and post-interview report.
- Built a real-time interview coaching tool that detects facial emotions and speaking dynamics, then generates a timeline and an interview report with feedback.
- Trained a custom YOLO model for face/region detection and integrated it with a PyTorch emotion classifier (75% test accuracy)
