Labeling Experience

Freelance Data Annotator & AI Trainer

MindriftImageBounding Box

As a Freelance Data Annotator & AI Trainer at Mindrift, I labeled diverse large-scale datasets for AI and machine learning model training. My work included bounding box, polygon, and semantic segmentation on images, RLHF for AI response rating, and technical code annotation tasks. I consistently achieved annotation accuracy rates above 95% and delivered high-quality data under robust review processes. • Performed bounding box, polygon, and semantic segmentation annotations on image datasets. • Labeled and reviewed image, text, and video data for supervised machine learning pipelines. • Completed RLHF tasks including rating, ranking, and rewriting AI-generated responses. • Annotated Python, JavaScript, and TypeScript code datasets with technical precision.

Data Annotator & Quality Reviewer

ImeritImageBounding Box

As a Data Annotator & Quality Reviewer at iMerit, I applied bounding box, keypoint, and NLP annotation techniques to diverse projects. My responsibilities included QA/QC reviews ensuring dataset consistency, and evaluation of model outputs with detailed rubrics. I also gained experience in NER, sentiment, and intent labeling tasks using leading annotation platforms. • Evaluated and reviewed instruction following (IF) and instruction compliance (IC) outputs. • Applied bounding box and keypoint annotations for computer vision and pose estimation. • Conducted QA on peer annotations and maintained annotation consistency. • Annotated NLP tasks including entity recognition, sentiment, and intent classification.
