Freelancer Overview

I began my journey in AI training with audio transcription and voice recording tasks, building a solid foundation in precision and linguistic nuance. As I progressed, I expanded into image classification, where I worked on identifying and labeling features in clear and pixelated imagery detailing the data annotation. Fine understanding of AI data pipelines. I also have experience in prompt engineering and evaluation. I’ve crafted and reviewed long, complex prompts in both Portuguese and English, covering a wide range of categories including mathematics. My work involves rating model responses using detailed, fine-grained criteria — a process that requires critical thinking and subject matter sensitivity.
