Freelancer Overview

I am a Computer Science student at Columbia University with hands-on experience in building and optimizing data-driven systems across multiple internships and projects. My background includes designing and refining APIs, automating data pipelines, and optimizing database performance for large-scale applications. I am proficient in Python, Java, R, and SQL, and have worked extensively with cloud platforms like AWS and Google Cloud, as well as tools such as Docker, Kubernetes, and Jenkins. My experience with backend and frontend development, combined with a strong foundation in statistics and applied computing, enables me to understand the importance of high-quality, well-annotated data for AI and machine learning applications. I am eager to contribute my skills in data labeling, annotation, and training data management to support robust AI solutions.

AI Response Evaluation & Structured Feedback

OtherImageRelationshipClassification
Contributed to AI training and evaluation workflows focused on improving large language model performance through structured human feedback. Tasks involved reviewing AI-generated responses to a wide range of prompts, evaluating outputs for factual accuracy, logical consistency, instruction adherence, tone, and completeness based on detailed rubrics. Provided written justifications explaining evaluation decisions, identified reasoning flaws or hallucinations, and suggested concrete corrections or improvements to align responses with user intent. Work required careful attention to nuanced instructions, domain knowledge in computer science and data systems, and consistent application of quality standards. Emphasis was placed on clarity, precision, and reliability of feedback to support reinforcement learning from human feedback (RLHF) and supervised fine-tuning processes.
