Key Skills

Freelancer Overview

I am a data analyst with a strong foundation in data processing, validation, and quality assurance, supported by hands-on experience in both operational and analytical roles. My background in industrial engineering and comprehensive training in data science have equipped me to work across the full data lifecycle—from cleaning and verifying raw data to developing and deploying machine learning models for tasks such as churn prediction and root cause analysis. I am proficient in Python, SQL, and libraries like Pandas, NumPy, and Scikit-learn, and I have practical experience with data visualization tools such as Tableau and Looker Studio. My work has involved meticulous data verification, annotation, and documentation to ensure accuracy and reliability, and I am comfortable applying techniques in NLP, computer vision, and time series analysis to support AI training data initiatives. I thrive in collaborative environments and am committed to delivering high-quality, actionable data that drives better decision-making.
