Labeling Experience

Advanced AI Model Trainer

As an Advanced AI Model Trainer on independent projects, I trained conversational AI models and evaluated their multilingual and domain-specific performance. I created structured prompt libraries, conducted red-teaming, and tested model robustness and response quality. I designed synthetic datasets for education, business, and creative reasoning tasks. • Developed adversarial prompts for robustness testing • Improved AI dialogue flow and clarity • Performed detailed evaluation across different domains • Conducted AI model stress and edge-case testing.

As an AI Training Specialist at Outlier AI, I trained large language models through reinforcement learning and supervised fine-tuning. I evaluated and rated AI responses on accuracy, reasoning, safety, and instruction following. I designed datasets and prompts to enhance model performance across language understanding, conversational flow, and reasoning tasks. • Conducted safety reviews and detected model hallucinations • Benchmarked AI models and created grading rubrics • Annotated and evaluated complex reasoning and coding tasks • Improved clarity, tone, and human-like responses in AI outputs.

AI Data Annotation Specialist

RemotasksImageSegmentation

As an AI Data Annotation Specialist at Remotasks/iMerit, I annotated text, image, and video datasets for computer vision and NLP projects. I performed semantic segmentation, object tagging, bounding boxes, sentiment analysis, and speech transcription labeling tasks. I participated in quality control, reviewed annotations, and trained new annotators for large-scale projects. • Labeled datasets for autonomous vehicles and OCR • Performed video scene and environmental condition tagging • Annotated conversational and handwriting recognition datasets • Completed high volume text and audio transcription with accuracy.
