Freelancer Overview

I am a detail-oriented AI training specialist with three years of hands-on experience in data labeling, annotation, and supporting model training across image, video, and audio datasets. My expertise includes preparing high-quality datasets for computer vision and speech processing applications, with a strong focus on object detection, tracking, and transcription. I am proficient in using industry-standard annotation tools such as Labelbox, CVAT, and Supervisely, and have practical experience working with the YOLO framework for real-time object detection. I consistently maintain high annotation accuracy and data integrity, having contributed to projects that improved detection model performance and supported AI-powered virtual assistants. I am committed to quality assurance, efficient workflows, and collaborating with cross-functional AI teams to deliver reliable training data for machine learning pipelines.

Remote Multi-Object Detection & Tracking for Retail Surveillance System

LabelboxImageBounding BoxPolygon
Worked on a large-scale computer vision dataset for a retail surveillance AI system designed to monitor in-store customer activity and inventory movement. Annotated over 120,000+ video frames and 45,000+ images using bounding boxes and multi-object tracking techniques. Labeled multiple object classes including persons, shopping carts, products, and restricted-area entries. Performed frame-by-frame tracking to maintain object identity consistency across sequences. Ensured accurate labeling for occlusions, motion blur, and low-light conditions. Collaborated with ML engineers to prepare datasets for training YOLO-based object detection models, improving detection accuracy and reducing false positives. Quality Control Measures: Maintained 98%+ annotation accuracy Followed strict labeling guidelines and class taxonomy Conducted peer-review validation Performed consistency checks across video sequences Verified bounding box tightness and correct object classification

Remote LLM Code Annotation & Evaluation for Programming Model Fine-Tuning

OtherComputer Code ProgrammingRLHFFine Tuning
Contributed to the development and fine-tuning of a Large Language Model (LLM) focused on computer programming and code generation tasks. Annotated and evaluated over 15,000+ programming prompts and responses across multiple languages including Python, JavaScript, Java, and C++. Tasks included grading model-generated code for correctness, efficiency, readability, and adherence to best practices. Performed: Code correctness validation (runtime + logic testing) Bug identification and categorization Writing high-quality reference solutions (SFT data creation) Ranking multiple model outputs (RLHF pairwise comparison) Red teaming to identify hallucinations and insecure code patterns Improving prompts for better instruction-following behavior Tested generated code in controlled environments to verify functionality and edge cases before final annotation submission. Quality Assurance Measures: Followed structured grading rubrics
