Freelancer Overview

I am a detail-oriented finance graduate with hands-on experience in data analysis, cleaning, and preparation, gained through intensive bootcamp training and practical projects. I have utilized tools such as Power BI, Tableau, SQL, and Excel to clean datasets, handle missing values, and ensure data integrity for accurate analysis and reporting. My work includes building interactive dashboards to visualize sales metrics and market trends, which required careful data annotation and validation to support actionable insights. I am passionate about contributing to data labeling and AI training data projects, bringing strong analytical skills, a collaborative mindset, and a commitment to maintaining high data quality in dynamic environments.

High-Precision Video Annotation for Autonomous Navigation (Atlas Capture)

Internal Proprietary ToolingVideoPolygonObject Detection
Performed frame-by-frame video annotation on the proprietary Atlas Capture platform to support the development of computer vision models. My work focused on identifying and tracking dynamic objects (pedestrians, vehicles, cyclists) across temporal sequences. Key responsibilities included: Applying Polygon masks and Polyline annotations with sub-pixel accuracy to define road boundaries and obstacles. Utilizing Object Tracking techniques to ensure ID consistency for entities moving through occlusions and variable lighting. Adhering to strict "Ground Truth" guidelines to maintain a 98%+ quality audit score. Identifying and reporting dataset edge cases, such as rare weather conditions or unconventional vehicle types.
