Freelancer Overview

I am an experienced AI data annotation and LLM training specialist with a strong background in text, audio, and image annotation for machine learning projects. My expertise includes text classification, sentiment analysis, audio transcription (including multi-speaker and timestamped transcripts), and image labeling with bounding boxes for computer vision datasets. I am highly skilled in following detailed guidelines, identifying edge cases, and ensuring high-quality outputs through systematic quality assurance and self-review processes. I have consistently maintained over 95% accuracy while meeting productivity targets in remote and asynchronous environments. My experience spans preparing structured datasets (CSV/JSON), metadata tagging, and contributing to supervised ML pipelines, and I am quick to adapt to new annotation tools and workflows. I am committed to delivering reliable, accurate data labeling that enhances model training and performance.

AI Text Annotation & Quality Evaluation for LLM Training

HumanaticTextClassificationRLHF
Worked on AI text annotation and response evaluation tasks to improve large language model (LLM) performance. Responsibilities included reviewing AI-generated responses for accuracy, relevance, clarity, and adherence to given guidelines. Performed classification of text outputs, rated model responses based on predefined rubrics, and identified inconsistencies or hallucinations. Contributed to supervised fine-tuning (SFT) by crafting high-quality prompt-response pairs and performing reinforcement learning from human feedback (RLHF) tasks. Ensured strict compliance with annotation guidelines, maintained high accuracy standards, and met daily productivity targets. Applied attention to detail and analytical reasoning to maintain data integrity and consistency across batches.
