Freelancer Overview
My day-to-day involves prompt engineering, reviewing and grading AI responses, and providing structured feedback to help improve the models. I also handle Swedish translations with a focus on linguistic accuracy and cultural relevance. My hands-on experience with complex rail operations and safety-critical protocols allows me to train AI models with an expert level of technical accuracy and domain-specific intuition that generalist annotators simply cannot match.
