Freelancer Overview

I have 3+ years of experience contributing to AI training data pipelines with a focus on evaluation, quality assurance, and reinforcement learning from human feedback (RLHF) for speech and conversational AI systems. AI evaluation and training data work (RLHF, speech/audio, multilingual) conducted continuously since 2022 across multiple projects. My work includes structured evaluation and scoring of AI-generated text and audio outputs, emotion recognition, response quality assessment, and safety alignment using detailed rubrics and annotation guidelines. I have supported supervised fine-tuning (SFT) and post-training evaluation by reviewing prompt–response pairs, validating annotation accuracy, and identifying systematic failure modes such as hallucinations, misclassification, and contextual drift. I have hands-on experience working with proprietary annotation platforms and spreadsheet-based review workflows to perform high-volume evaluations, secondary reviews, and QC audits. I conduct multilingual assessments (English, Hindi, Bengali) to ensure linguistic and cultural correctness, and regularly flag false positives/negatives to improve model precision and recall. In addition to execution, I provide structured feedback and aggregated insights to refine evaluation criteria and improve consistency across annotators, contributing to more reliable training data and measurable improvements in model performance.
