Experience
Advanced Manufacturing Engineer - Co-op
Bendix Commercial Vehicle Systems
Jan 2026 - Present | Avon, OH
- Implemented a Boston Dynamics Spot inspection program, translating maintenance requirements into 450+ SAP-aligned inspection points.
- Built a Python/MSSQL integration layer that normalizes 11 Orbit API resource types into a 16-table schema and maps robot inspection data to the SAP asset hierarchy.
- Designed light-and-sound behaviors that signal robot state and direction, turning shop-floor feedback into a production feature.
- Fabricated 120+ 3D-printed AprilTag plates for Spot localization, reducing 3d modeling time from ~2 hours to 2 minutes and unit cost from approximately $16 to $2 per tag.
Weather AI Research Intern
xLab @ CWRU - Industry Partner: Progressive
Jun 2025 - Aug 2025 | Cleveland, OH
- Developed an HPC weather-model pipeline with Python and NVIDIA Earth2Studio, generating 7-day global forecasts in under 3 minutes.
- Evaluated FourCastNet, StormCast, CorrDiff, and cBottle for extreme-weather forecasting, presenting tradeoffs to stakeholders.
Frontend Developer - AI Call Center Training System
xLab @ CWRU - Industry Partner: Eaton
Jan 2025 - May 2025 | Cleveland, OH
- Built frontend components with Next.js, TypeScript, and Material UI for an AI call-center training platform (FastAPI backend).
Squad Leader / IT Technician (Signaler)
Republic of Korea Army
Jan 2023 - Jul 2024 | South Korea

Projects
Language-Guided Bimanual Manipulation with NVIDIA GR00T N1.5
CWRU Senior Capstone
Jul 2025 - Dec 2025
- Engineered a 12-DoF bimanual SO-101 embodiment in LeRobot with leader-follower teleoperation and a three-camera capture stage.
- Collected 360 synchronized teleoperation episodes across 12 configurations after diagnosing timestamp misalignment and discarding approximately 200 corrupted episodes.
- Fine-tuned GR00T N1.5-3B on H200/L40S GPUs, raising task success from 0% untuned baseline to ~25%
- Cut training time from a projected 15 hours to 2.5 by profiling video decoding and tuning batch size and data-loader parallelism.
Environmental & HR Data Pipelines (CSDS 397: Data Pipelines & Visualization)
Jan 2025 - May 2025
- Architected a Python/Airflow pipeline automating environmental data ingestion, producing interactive Tableau air-quality dashboards.
- Engineered dbt ELT transformations to cleanse and validate HR datasets, deploying 6 tested models with automated refresh.
