Freelancer Overview

I am an AI Training Specialist with over three years of hands-on experience in data labeling, annotation, and dataset preparation for machine learning and AI projects. My background includes extensive work with image, video, and audio annotation, supporting computer vision workflows such as object detection, tracking, semantic and instance segmentation, and speech transcription. I am proficient in industry-standard tools like Labelbox, CVAT, Supervisely, V7 Darwin, Scale AI, and Amazon SageMaker Ground Truth, and I prepare datasets in COCO and Pascal VOC formats to ensure seamless integration with model training pipelines. My technical skills include Python for data preprocessing and automation, as well as familiarity with OpenCV, JSON, and XML. I excel at maintaining annotation quality and consistency, conducting thorough dataset validation, and collaborating with machine learning engineers to enhance data quality and model performance. I am passionate about delivering precise, high-quality training data and thrive in remote, deadline-driven environments.

LLM Text Evaluation and AI Response Quality Rating

AppenTextClassificationText Generation
Worked as an AI Quality Analyst on a short-term Large Language Model (LLM) evaluation project focused on improving AI-generated text quality and safety. Reviewed and analyzed thousands of prompt-response pairs, carefully evaluating outputs for accuracy, factual consistency, relevance, coherence, clarity, tone, and compliance with safety policies. Assigned structured classification labels and quality ratings based on detailed annotation guidelines, ensuring consistent evaluation standards across batches. Identified hallucinations, biased responses, harmful content, and logical inconsistencies, providing actionable feedback to support Reinforcement Learning from Human Feedback (RLHF) and fine-tuning processes. Participated in random audits and quality checks to maintain high inter-annotator agreement and labeling accuracy. Successfully evaluated over 5,000+ text samples while meeting strict turnaround deadlines, contributing to measurable improvements in model reliability.
