Data Logic Verification & Quality Assurance Intern

Text

As a Data Logic Verification & Quality Assurance Intern, I implemented data quality procedures to ensure high-accuracy dataset validation for AI systems. I developed and executed cross-departmental mechanisms to assess data logic and correctness across large text-based datasets. My efforts enhanced the reliability of data used for AI model training, contributing to improved model performance. • Conducted rigorous correctness verification and anomaly detection on regional asset datasets. • Standardized and refined data verification and error correction protocols. • Pioneered dynamic data grid management for real-time error reduction. • Achieved a substantial decrease in data inconsistencies impacting model outputs.

Data Processing & System Integration Intern

Text

During my internship on the Traffic Safety Digital Upgrade project, I led comprehensive data cleaning and quality assessment of structured text data. I designed multi-level inspection processes to eliminate data inconsistencies, errors, and hallucinations within historic records for use in digital systems. My efforts ensured that only high-quality, reliable data would be available for future digital AI applications. • Developed and implemented a 3-step quality assurance pipeline. • Resolved significant historical data conflicts during preprocessing. • Utilized Python/VBA for data preprocessing and consistency checking. • Enhanced first-pass accuracy for 5,270+ text records for downstream AI use.
