What I'm looking for

I want to enhance my AI/annotation skills in an organization that values hard work—trusted with responsibilities and challenges—where I can deliver accurate labeling and language evaluations that improve AI responses.

I’m an AI Trainer / Data Annotator focused on enhancing AI performance by “Rate and compare AI responses” and “Label data to improve AI accuracy.” I bring a detail-focused, repetitive work ethic, balancing speed with quality across “image annotation,” “text annotation,” and “audio and video labeling.”

In my projects, I reviewed and refined AI-generated text to improve “grammar, clarity, tone, and coherence,” using “language quality assessment, rewriting, and response optimization.” The results were “Enhanced the accuracy, readability, and natural flow of content,” contributing to “more consistent and human-like AI responses.” With a B.A. in English and Literary Studies (3.50), I pair strong reading comprehension and writing/editing skills with “basic understanding of AI/ML,” “computer literacy,” and data annotation tools.
