Freelancer Overview

I have nearly 2 full years of experience training LLM's including Gemini, ChatGPT, and Claude. The vast majority of my experience has come on the Data Annotation platform, with a small amount on Labelbox. Due to my diligence and expertise, I was recognized by the DA platform as one of their top workers and was granted access to high-level projects. I have participated in a wide variety of projects, mainly evaluating text-based conversations, but I have worked with audio, image, and video input/outputs as well. I excel at thoroughly assessing LLM outputs based on safety, factuality, instruction following, helpfulness, relevance, tone, format, and conciseness. I am adept at crafting complex user prompts (and/or system prompts) that push the LLM's abilities to its limits, particularly in the Math/STEM fields. When applicable, I also edit model responses for improvement. This is generally well within my abilities since I am comfortable formatting with Markdown, LaTeX, and plain text. I speak and write fluently in English and Spanish, enabling me to produce high-level work in bilingual and/or translation projects. Apart from strictly LLM training, I am skilled in technical writing, deep research, fact-checking, data analysis and presentation, and Microsoft Office / Google tools. I produce original, authentic, high-quality work in a timely manner.
