TextPrompt Response Writing SFT
As an AI Tester and Prompt Engineer, I engineered prompt frameworks for large language models to automate complex tasks. I performed model training by testing various apps and websites to ensure AI-generated content met brand and accuracy requirements. I authored documentation and UI copy to bridge back-end logic and user-facing instructions. • Developed and refined high-precision prompts for supervised fine-tuning. • Evaluated and rated AI model responses for quality and correctness. • Utilized internal or proprietary tools for prompt testing and annotation. • Conducted detailed quality assurance and iterative feedback for LLM outputs.
