Labeling Experience

AI Application Engineer, Data Curation and Fine-tuning

ImageFine-tuning

As an AI Application Engineer, I was responsible for generating images using AI tools based on specific text prompts and style requirements. I curated, reviewed, and prepared a variety of training data types, including images, text, and structured data, to be used for model fine-tuning. In addition, I performed validation of model outputs, refining prompts and parameters to meet project standards. • Generated synthetic images for AI training purposes. • Fine-tuned datasets by careful selection and preparation of input/output pairs. • Reviewed and evaluated data quality for accuracy and consistency. • Used internal or proprietary tools to support annotation and data curation.
