Freelancer Overview

With a solid foundation in Systems Engineering and over 12 years of professional experience in IT project management and digital transformation, I have developed a strong analytical mindset and a meticulous attention to detail, which are crucial for high-quality data labeling and annotation. My hands-on experience includes implementing AI solutions for marketing optimization, which involved data analysis, segmentation, and process automation using Python and data visualization tools like Tableau. I have managed the full lifecycle of AI-based projects, from requirement gathering to delivery, ensuring accuracy and alignment with project goals. My recent certification in Python for Data Science and Applied Artificial Intelligence in Business has further strengthened my technical skills for data training tasks, including text analysis and classification for NLP projects. I am adept at following complex guidelines and thrive in ensuring data consistency and reliability for training robust AI models.

Labeling Experience

Factual Accuracy Evaluation for Generative AI Responses

Internal Proprietary ToolingTextClassificationLand Cover Classification
This project involved the critical evaluation and labeling of text responses generated by a large language model (LLM) for factual accuracy. The scope required analyzing a diverse dataset of prompts and responses covering topics such as sports history, scientific concepts, and music trivia. My specific labeling tasks included: Performing binary classification, tagging each response as "Accurate" or "Contains Inaccuracy." Conducting thorough fact-checking by cross-referencing every claim against reliable, verifiable sources. Identifying and categorizing specific error types, including conceptual inaccuracies (e.g., misidentifying a natural mineral as synthetic), factual data errors (e.g., attributing a solo artist's work to a band), and typographical errors in proper nouns. Strictly adhering to detailed client guidelines to ensure consistent and unbiased judgment across all data points. The project involved a deliverable dataset for a key client.

Medical & Safety Information Verification for AI Assistant

Scale AITextClassification
Focused on the critical area of AI safety, this project involved labeling and verifying AI-generated responses to user queries on medical and hazardous materials. The primary goal was to identify and flag potentially harmful misinformation. My responsibilities included: Content Classification: Labeling responses based on potential harm (e.g., "Safe," "Medically Unsound," "Potentially Dangerous"). Information Verification: Checking the accuracy of health-related information (e.g., properties of asbestos, side effects of medications) against established medical and scientific databases. Safety Filtering: Identifying responses that contained unverified claims or could lead to unsafe actions if followed by a user. Adherence to Strict Protocols: Following complex, multi-step guidelines to handle sensitive topics with the required caution and accuracy. The project comprised a large dataset of thousands of query-response pairs.
