As an AI Prompt Engineer at Fiverr, I designed and managed production prompts for LLM applications including tasks like question answering, classification, tagging, entity extraction, summarization, paraphrasing, text cleaning, and ranking. I implemented human-in-the-loop quality assurance for LLM-generated content and trained teams on related processes. Model behavior was analyzed for improvement insights while collaborating cross-functionally. • Managed full lifecycle for prompts in production environments. • Designed prompt templates and cataloged their structure. • Evaluated LLM outputs and adjusted prompt parameters. • Trained internal and freelance teams on prompt QA methodologies.
