Freelancer Overview

I am a mathematics and computing undergraduate with a strong foundation in machine learning, deep learning, and natural language processing. My hands-on experience includes fine-tuning transformer models like DistilBERT for sentiment classification, where I worked extensively with the IMDb dataset and achieved high validation and test accuracies using parameter-efficient techniques. I am skilled in Python, C++, and widely used libraries such as Pandas, Numpy, PyTorch, TensorFlow, and Hugging Face Transformers, which I have leveraged for data preprocessing, annotation, and model training tasks. My projects have required meticulous data handling, labeling, and validation, ensuring high-quality training data for robust AI models. I am passionate about building reliable AI systems and am eager to contribute my expertise in data labeling and annotation to impactful projects.
