AI Training and Annotation Projects (Independent)

TextClassification
In self-led AI-related projects, I simulated AI workflows including data classification, annotation, and validation using diverse texts. I developed and evaluated prompt-based interaction systems for model response quality. These activities built practical infrastructure for classifying and annotating training datasets for machine learning models. • Labeled and classified data for use in model training and evaluation • Created workflows for supervised learning tasks in NLP • Assessed and validated AI-generated text outputs for accuracy • Designed practical annotation frameworks in data science projects

OtherTextPrompt Response Writing SFT
As a freelance technical contributor, I produced AI prompt engineering tutorials and contributed to the creation of response datasets. I translated complex AI and programming concepts into accessible written content designed for AI model training and evaluation. This role involved synthesizing and documenting high-quality prompts and sample responses for natural language models. • Authored and curated text data for training and evaluating AI response systems • Generated example prompts and responses for language model fine-tuning • Ensured accuracy and clarity in technical materials and datasets • Contributed to educational resources for AI and data science platforms
