Freelancer Overview

I am an AI data specialist with hands-on experience in data labeling, annotation, and LLM output evaluation. My work has focused on reviewing AI-generated content for logical consistency, factual accuracy, bias detection, and instruction alignment, ensuring high-quality datasets for AI training and evaluation. I am skilled in using Python, SQL, and tools like TensorFlow, Scikit-learn, and Power BI, and I have built and validated structured datasets for machine learning workflows. My projects include developing a digit classifier using CNNs and creating analytics dashboards, where I emphasized accuracy measurement and data quality. I am detail-oriented, thrive in precision-driven environments, and consistently maintain robust documentation to support reproducible and reliable AI systems.

Speech Transcription and Audio Quality Evaluation for AI Training

Internal Proprietary ToolingAudioText GenerationEmotion Recognition
Worked on speech-to-text evaluation and audio annotation tasks to improve automatic speech recognition (ASR) systems. Transcribed multilingual audio samples with high accuracy, ensuring correct punctuation, speaker clarity, and contextual consistency. Reviewed audio outputs for pronunciation errors, background noise impact, and alignment between spoken and transcribed text. Rated audio quality and categorized recordings based on clarity, speaker intent, and emotional tone. Maintained strict quality standards while handling diverse accents and varying audio conditions to support robust AI model training.
