Freelancer Overview

I have experience in AI training data, starting as a content reviewer and later contributing to large language model (LLM) evaluation projects. My work involved assessing model outputs for quality and accuracy, as well as creating diverse and effective prompts to enhance AI performance. This hands-on experience has given me a strong understanding of data labeling standards and best practices. Key skills that set me apart include data quality assessment and prompt engineering, ensuring AI models generate accurate and meaningful responses. Additionally, my background as a writer and copywriter has honed my communication skills, allowing me to craft precise text and provide clear feedback in different AI training workflows.

I worked on a project focused on evaluating large language models (LLMs) to ensure their responses met quality, accuracy, and alignment standards. The project involved crafting structured prompts with specific constraints to guide the model’s behavior and assessing its outputs against predefined client objectives. My data labeling tasks included: Prompt Engineering – Creating prompts that tested the model’s ability to follow constraints and generate high-quality responses. Response Evaluation – Reviewing AI-generated text for accuracy, coherence, relevance, and adherence to guidelines. Correction & Refinement – Modifying responses when they failed to meet quality standards, ensuring compliance with client expectations. To measure quality, we followed client-defined evaluation metrics, including accuracy, clarity and truthfulness.
