Freelancer Overview

I am a Machine Learning Engineer with hands-on experience in large language model (LLM) training, data labeling, and dataset curation for NLP applications. My work includes preparing and refining large-scale datasets using advanced pipelines such as CC-Net, GoClassy, and Ungoliant, with custom modifications to enhance data filtering and quality scoring. I have developed and trained classifiers to label pretraining data by quality, ensuring high standards for AI training data. My technical toolkit spans Python, Rust, PyTorch, and Hugging Face, and I have designed end-to-end data pipelines for model pretraining, fine-tuning, and evaluation. I am passionate about optimizing data workflows, implementing scalable preprocessing systems, and leveraging retrieval-augmented generation (RAG) for domain-specific applications, including finance and code generation. My background in model architecture, dataset collection from diverse sources, and real-world deployment of AI solutions enables me to deliver high-quality, reliable training data for advanced machine learning projects.
