Data Annotation Specialist (Freelance/Contract)

OtherImageClassificationEntity (NER) Classification

I completed text annotation exercises including NER, intent classification, sentiment labeling, and instruction-following quality assessment using public AI training documentation. I evaluated and ranked AI-generated responses for correctness, helpfulness, tone, and safety, simulating RLHF feedback workflows. I annotated image datasets for object detection and region segmentation, ensuring consistent standards across batches. • Applied real-world annotation guidelines for diverse NLP tasks. • Conducted RLHF-style LLM output evaluation for simulated feedback. • Performed object detection and segmentation on image datasets as practice. • Maintained a personal prompt engineering log with 30+ tested prompts.
