I contribute to the development and improvement of Large Language Models (LLMs) by providing accurate data labeling, linguistic analysis, and quality assurance review. My work ensures that AI systems better understand human language with precision, context, and cultural nuance.

Key Responsibilities:

Data Annotation: Label, categorize, and validate large volumes of text data for NLP tasks such as intent classification, sentiment analysis, entity recognition, and text generation.

Quality Assurance (QA): Review and audit other annotators’ work to maintain accuracy, consistency, and adherence to project guidelines. Provide detailed feedback and ensure final dataset integrity.

AI Training: Evaluate and refine AI-generated responses by giving structured feedback to improve language understanding, tone, and reasoning quality.
