Key Skills

Freelancer Overview

I have experience working with AI systems, machine learning workflows, and data preparation processes that are closely related to AI training and data labeling. During my AI internship, I worked on an AI-powered chatbot where I tested model responses, identified edge cases, improved prompt structures, and helped optimize response quality. This required reviewing outputs, validating response accuracy, and ensuring consistency across different user scenarios. In addition, I developed a Hybrid GA–Longformer Spam Classification System, where I worked extensively with dataset preprocessing, cleaning, labeling validation, feature engineering, and model evaluation. I used Python, Pandas, NumPy, PyTorch, and Hugging Face Transformers to prepare data, optimize features, and improve classification performance. These experiences gave me a strong understanding of data quality, annotation accuracy, model evaluation, and the importance of well-structured training data in building reliable AI systems.
