Freelancer Overview

I have 4 years of hands-on experience in data processing, annotation, and service planning within the ICT and food safety domains. My work has included data cleaning, validation, and structuring for R&D projects, as well as collaborating on AI-related initiatives such as machine learning-based decision tree development and feasibility analysis. I am skilled in statistical analysis, PL/SQL, and data visualization (Tableau), and hold certifications including SQLD and Information Processing Engineer. I have managed the full cycle of data-centric projects—from requirements gathering and data collection to documentation and user training—ensuring high-quality, reliable datasets for platform development and AI solutions. My background enables me to quickly adapt to new domains and deliver accurate, well-organized training data for AI and data science projects.
