Isaac Polonio

I’m a Business Intelligence Analyst and Software Engineer who turns enterprise data into measurable business results through reporting automation, analytics, and modern data pipelines. I’m hands-on with Power BI and SQL, and I focus on improving both decision speed and operational efficiency. At EGE Haina, I rebuilt more than 15 abandoned reports, reducing operational costs by 10% and processing time by 30%. I partnered with Finance to automate EBITDA, budget, and cost reporting across the company, and I implemented SAP Datasphere to integrate HR data from SuccessFactors—cutting reporting time by 50%. I also built ETL pipelines using Microsoft Fabric, SAP Datasphere, Python, and Power Automate to streamline data preparation and delivery. I apply DAX to create business-focused measures and KPI formulas for executive reporting, and I developed PostgreSQL views for the Gold layer to improve data access consistency. My analytics work includes SQL in Trino for ad hoc analyses and operational insights across insurance and energy operations, including net revenue and generation metrics across multiple plants. I even designed and implemented a custom Trino connector for a modern Iceberg-based lakehouse architecture, reinforcing my preference for end-to-end, reliable data delivery.
