ABOUT LEO MIRANDA
As a Senior Data Analyst at Summitt Energy with 6+ years of experience, I design and manage enterprise analytics infrastructure that supports a retail energy company with operations across Canada and U.S. markets. Leveraging skills in Python, SQL, and dbt, I develop dimensional data models, engineer scalable ETL pipelines, and create actionable dashboards with tools like Power BI and Plotly-Dash to empower cross-functional teams spanning Customer Service, Compliance, Sales, and Executive leadership. My work emphasizes automation, operational efficiency, and actionable insights, demonstrated by contributions such as a 30% improvement in call abandon rates and a 50% reduction in Average Speed to Answer. Outside of Summitt Energy, I provide automation and AI-driven solutions to small businesses through my consultancy, Hyper Hive Labs, where I build tools like OCR-based receipt processing systems and AI-guided development frameworks. My mission is to create data solutions that are efficient, impactful, and practical for decision-making.
