I am an experienced Data Annotator in the field of Natural Language Processing using Reinforced RLHF (Reinforcement Learning from Human Feedback). My primary focus is on training and improving AI language models by generating prompts and desired responses for training data, performing quality checks on annotated data, and extracting relevant data for analysts. In addition, I prepare original, creative content to be used in the desired responses as well as various other tasks in accordance with project guidelines. I have also learned to use my prompting skills to create different personas for chatbots using pre-trained models. Before transitioning to the field of data annotation and NLP/RLHF, I spent 20 years working as a paralegal in Connecticut. In 2016, I decided to pursue my passion for petsitting, and I moved to California and started my own successful business. Recently, I decided that I wanted to explore the possibility of working remotely in conjunction with the petsitting. That's when I discovered data annotation and prompt/content creation working with NLP language models. I was immediately drawn to the field and found that my attention to detail and excellent communication skills are valuable assets in this line of work. Through my diverse background and experience, I bring a unique perspective and skill set to my work as a data trainer/annotator. I'm committed to delivering high-quality data that supports the development of accurate and effective AI language models.
