Freelancer Overview

I am a Senior Data Analyst with hands-on experience in transforming raw data into actionable insights, particularly through building robust data pipelines and implementing data lakes using medallion architecture. My work has involved integrating and unifying diverse data sources, automating data processing with Python and SQL, and developing interactive dashboards for real-time analytics. I have applied both descriptive and predictive analytics to support AI-driven automation and strategic decision-making, including optimizing marketing and CRM data, tracking key performance metrics, and automating reporting workflows. My technical expertise spans Python, SQL, Power BI, BigQuery, and cloud platforms such as AWS and GCP, and I am passionate about leveraging data engineering and analytics to improve AI training data quality and support machine learning initiatives.
