Labeling Experience

Video Data Annotation for AI Training

VideoBounding Box
I performed video data annotation by labeling human faces, heads, and upper bodies across video frames to create structured computer vision training datasets. I precisely drew bounding boxes for each object in every frame and ensured consistent frame-by-frame labeling to meet dataset quality standards. This labeling supported the training and improvement of AI models for human detection. • Annotated video frames with bounding boxes for face and body detection • Ensured consistent labels across sequential video frames • Supported computer vision dataset creation for AI model development • Maintained data quality through rigorous annotation and review processes.

LLM Trainer—Data Annotation Specialist

TextRLHF
As an LLM Trainer—Data Annotation Specialist, I applied Reinforcement Learning from Human Feedback (RLHF) and supervised fine-tuning techniques to improve large language model (LLM) performance. I evaluated LLM responses for reasoning, factual accuracy, and instruction-following to enhance output quality. I generated and curated high-quality datasets to support fine-tuning and overall AI model improvement. • Conducted RLHF-based training and supervised fine-tuning on LLMs • Evaluated AI model outputs based on multiple reasoning and QA benchmarks • Generated, reviewed, and curated text datasets for model training • Collaborated with AI teams to refine annotation guidelines and evaluation pipelines.
