Freelancer Overview

I have hands-on experience in AI training data and annotation projects, including my role at Outlier, where I refined prompts and evaluated AI-generated outputs across platforms like ChatGPT and Claude. I’ve also contributed to voice-based and linguistic data collection initiatives via VoiceHub and similar platforms, ensuring accuracy, consistency, and adherence to project guidelines. My background in engineering and training in machine learning and AI fundamentals gives me a strong grasp of data quality standards and annotation tools. I combine technical skills with clear communication and attention to detail in every task.
