Hello, I'm
Bisiriyu Esther Temitope
Data Analyst | Power BI Developer | Data Visualization
I am a Data Analyst who helps businesses transform structured and unstructured data into insights that drive performance and growth. My focus is on transforming data into meaningful stories that highlight what is working, what is not, and where opportunities exist. Before starting any analysis, I take time to understand the business context, your goals, key challenges, and performance drivers, so that every insight I deliver is relevant, practical, and aligned with real business needs. I specialize in building interactive Power BI dashboards and structured data solutions that help teams track performance, monitor KPIs, and make confident, data-driven decisions.
My work covers the full data workflow, including data preparation and engineering, where I design ETL processes and clean datasets using Power Query and SQL to ensure accuracy and consistency. I also focus on data modelling by structuring data into scalable models with clear relationships and measures for efficient reporting. In addition, I handle visualization and reporting by creating interactive Power BI and Excel dashboards that simplify complex data and highlight key KPIs. Through exploratory data analysis using SQL, I uncover trends, patterns, and insights that support informed business decisions and strategy.
