Gerald Nnamdi

I am an AI language specialist and trained linguist with over five years of experience in language research, data annotation, and content development. I focus on improving AI model accuracy, text quality, and cultural relevance across multilingual projects.

As a freelance Linguist AI Trainer, I annotate and evaluate datasets, create training guidelines for LLM fine-tuning, and collaborate with data scientists to refine prompts and model outputs. I conduct quality assurance to detect bias, ambiguity, and grammatical issues while providing morphosyntactic and semantic insights.

Previously, I worked as a Research Assistant and Linguistic Editor at a marketing firm where my editing and content development increased engagement by 30%. I supported sentiment analysis, corpus annotation, part-of-speech categorization, and helped develop digital lexicons and phonetic transcription systems.

I also have teaching and graduate-assistant experience supporting students, proofreading academic work, and assisting research efforts. I bring strong technical proficiency with tools like Label Studio, Python, PostgreSQL, ChatGPT, and a practical grounding in NLP, corpus linguistics, and prompt design.
