Labeling Experience

System Developer & Data Reviewer (CubeSat Remote Sensing Research Project)

Other

Served as a system developer and data reviewer for a CubeSat remote sensing research project, supporting verification of telemetry data pipelines and system logic. Conducted system-level simulations to validate communication pathways and data flow correctness, and produced documentation describing system configurations and logic paths. While not performing manual annotation, the work functioned as AI/data pipeline quality review through rigorous testing and verification of data products used in downstream modeling or analysis.• Supported hardware-software integration and system testing for satellite telemetry data.• Performed MATLAB and STK simulations to verify communications logic and data pipelines.• Reviewed and documented configuration details and logic path analyses for a multidisciplinary team.• Ensured data pipeline correctness via simulation and system-level verification.

Machine Learning Systems Developer (AI-Based Loan Repayment Prediction System)

Other

Developed and evaluated an end-to-end ML loan repayment prediction system using financial and demographic datasets, emphasizing input validation and fixing data inconsistencies before modeling. Performed rigorous model evaluation using precision metrics to confirm an accuracy target and adjusted preprocessing steps such as missing-parameter handling and constraint validation. Built a Streamlit interface with strict client-side validation to align raw data arrays with user inputs, reducing logic mismatches during training and testing.• Built ML training/evaluation pipelines for loan repayment prediction with precision-based assessment.• Implemented data preprocessing, constraint validation, and categorical encoding to improve dataset quality.• Designed interactive validation in a Streamlit app to ensure correct input formats during experimentation.• Resolved logic mismatches between backend data structures and frontend user inputs.
