Profile Description

I specialize in the intersection of linguistics and machine learning. I understand that the quality of an AI model is entirely dependent on the quality of its training data. I don't just "label"—I analyze, refine, and optimize.

Core Competencies:
RLHF (Reinforcement Learning from Human Feedback): Expert in ranking model responses, identifying hallucinations, and fine-tuning AI personality/tone.

NLP Specialization: Skilled in Named Entity Recognition (NER), Sentiment Analysis, Part-of-Speech (POS) tagging, and Intent Classification.

Prompt Engineering & Evaluation: Crafting complex prompts and evaluating model outputs for "helpfulness, honesty, and harmlessness" (HHH criteria).

Complex Constraint Following: Experienced in testing models against strict multi-turn instructions and logic puzzles.

Tools & Technical Skills:
Platforms: Scale AI (Outlier), Remotasks, Labelbox, Toloka, and CVAT.
Communication: Slack, ---------- , and Trello for seamless team integration.
Data Handling: Proficient in Google Sheets/Excel for tracking large datasets.

My Commitment:
I offer a meticulous eye for detail and a deep understanding of nuance. Whether it's identifying subtle biases in a chatbot's response or accurately labeling thousands of text strings for a new NLP model, I deliver data that is clean, consistent, and ready for production.
