Korean AI Evaluation | Data Quality | LLM Operations
I’m a data and AI operations professional with experience in data engineering, data quality, automation, and AI-related workflows. I can support projects involving Korean language data, AI response evaluation, data validation, annotation, localization QA, and structured data processing. My strengths are accuracy, clear communication, and building reliable workflows for data and AI projects. I’m especially interested in projects related to LLM evaluation, Korean AI data, and human-in-the-loop operations. I’m available for both individual tasks and team-based projects, and I’m focused on delivering consistent quality and meeting deadlines. I’m also building a Korea-based AI evaluation and human data operations team for larger-scale projects.
