Freelancer Overview

I have 3+ years of hands-on AI prompt engineering and AI output evaluation experience through my self-employed work on PromptBase, where I created, tested, optimized, and sold prompts for chatbots, image generation, and video generation. My prompts have generated 600+ sales with a 4.7-star customer rating, which required strong attention to detail, iterative testing, quality control, and the ability to judge whether AI outputs are accurate, useful, natural, and aligned with user intent. In addition, I have practical experience building AI-assisted no-code automation workflows using Make.com, Gemini AI, Google Sheets, Gmail, JSON parsing, and workflow routing logic. These projects helped me develop strong skills in evaluating AI-generated outputs, checking structure and consistency, identifying errors, and improving prompts or instructions to get better results. I am a native German speaker, fluent in English, and I work well independently in remote, task-based environments.
