Marsel Pongdatu Luase

I am a seasoned professional with over 19 years of experience in data management and process optimization, transitioning from a long career in public administration to a focus on Data Analytics and Business Intelligence.
My journey with data began in 2005, where I led the massive digitalization and verification of healthcare data for 500,000+ citizens in North Sulawesi—converting manual, handwritten records into a national digital database. This early experience instilled in me a deep commitment to data integrity and accuracy.
Today, I leverage modern analytical tools to transform complex datasets into actionable insights. I specialize in:
Data Engineering & ETL: Implementing Medallion Architecture Bronze, Silver, Gold to build robust data warehouses.
Analytics & BI: Creating intuitive dashboards in Tableau and Google Looker Studio.
Technical Stack: SQL, Python Pandas, BigQuery, and Advanced Excel.
Process Optimization: Proven track record of reducing operational processing times b
