Freelancer Overview

I am a detail-oriented AI Training specialist and content professional with extensive experience in technical quality rating, data annotation, and RLHF (Reinforcement Learning from Human Feedback). I specialize in assessing AI model outputs for accuracy, safety, and natural language fluency. My background as a multi-disciplinary content creator and digital marketer allows me to provide high-level nuance when evaluating creative writing, transcription, and complex prompt engineering tasks, ensuring that training data meets the highest linguistic and technical standards.

Creative Content Evaluation

VideoEvaluation Rating
I leveraged my professional background in videography and digital marketing to evaluate the quality and engagement of AI-generated creative assets. My work focused on auditing AI outputs for storytelling nuance, ensuring scripts and social media copy maintained a consistent and compelling brand voice. I specialized in assessing multimedia prompts, providing feedback on cinematography, pacing, and visual composition to refine text-to-video generation. By identifying and correcting subtle issues in emotional resonance and cultural context, I helped the model better understand human creativity. This expertise ensured that the training data produced professional-grade content capable of meeting real-world marketing standards.

RLHF & Quality Rating

DocumentRLHF
I contributed to the development of Large Language Models by performing multi-dimensional quality assessments through Reinforcement Learning from Human Feedback (RLHF). My primary role involved evaluating model-generated responses for factuality, safety, and strict adherence to complex instructions. I conducted side-by-side comparisons and ranked outputs to refine the model's logical reasoning and minimize hallucinations. Additionally, I crafted diverse prompts to identify edge cases and ensured all content remained helpful, harmless, and professional. By auditing linguistic flow and verifying technical claims, I helped deliver high-quality datasets that drive model reliability.

AI annotation

AudioTranscription
This project involved the high-fidelity transcription and speaker diarization of podcast audio to enhance Speech-to-Text and NLP models. I performed verbatim transcription, precise timestamping, and metadata tagging while accurately identifying multiple speakers in dynamic conversational settings. Over a 13-month period, I successfully processed a high volume of diverse audio content, ensuring all data was structured for machine learning. I maintained a strict 98% accuracy standard through systematic self-audits and phonetic cross-referencing of specialized terminology. Finally, I ensured full compliance with technical guidelines to deliver high-quality, machine-ready datasets for AI development.
