Labeling Experience

AI Data Trainer (Freelance / Remote)

LabelboxTextPrompt Response Writing SFT

As an AI Data Trainer, I labeled and validated text, image, and audio datasets for generative AI and computer vision training. I created and tested prompts for model alignment and provided feedback to improve model outputs. Rigorous quality assurance was conducted to maintain high accuracy standards. • Labeled large multilingual datasets • Developed prompts for instruction tuning • Performed quality reviews and accuracy checks • Used multiple labeling platforms including Labelbox and SuperAnnotate

AI Model Evaluator

AppenText

As an AI Model Evaluator, I assessed AI-generated responses for accuracy, safety, and relevance. I compared outputs, ranked responses, and identified hallucinations or bias in large language model outputs. Structured feedback was provided to support model improvements and ensure high-quality standards. • Evaluated responses for accuracy and adherence to guidelines • Identified hallucinations, bias, and misinformation • Provided feedback loops to model developers • Used prominent AI platforms and internal tools for workflow

Personal AI Project – Street Image Dataset Annotation

LabelimgImageBounding Box

In my personal AI project, I independently built and labeled a dataset of street images for object detection. I annotated images using bounding box methodology and validated accuracy through iterative model training on YOLOv5. This project demonstrated practical skills in structured annotation and supervised model development. • Designed and applied custom annotation guidelines • Labeled various street objects for model training • Integrated iterative validation using YOLOv5 framework • Focused on enhancing real-world model accuracy
