AI data annotation and ML support specialist improving LLMs through high-quality dataset preparation and evaluation.
What I'm looking for
I am an AI data annotation and machine learning support specialist with over 3 years of experience improving LLMs and NLP systems. I focus on dataset preparation, prompt testing, annotation quality, and evaluation to increase model accuracy and relevance.
My experience includes large-scale prompt testing, intent recognition, sentiment analysis, and supporting training pipelines for generative AI applications. I have provided structured feedback for iterative model improvement and contributed to quality assurance and classification accuracy efforts.
In roles at Remotask, OneForma, and App Work I assisted with training and deployment of LLM-powered applications, conducted user experience testing for chatbots and virtual assistants, and collaborated with engineers to refine AI-driven workflows using user feedback.
I bring strong attention to detail, time management, collaboration in remote teams, and hands-on experience with AI tools such as ChatGPT, Claude, Bard, and MidJourney. I am seeking opportunities to apply my annotation, prompt evaluation, and ML support skills in innovative AI or NLP teams.
