I build Power BI and Tableau dashboards that help businesses track performance, improve reporting accuracy, and reduce manual work. With 10 years of experience and 300+ completed projects, I develop reliable business intelligence systems and automate reporting using Power BI, Tableau, SQL, Python, and Microsoft Fabric. As a BI specialist and analytics engineer, I build SQL data models, semantic models, and automated data pipelines that give your Power BI and Tableau dashboards a reliable data foundation. If your data is spread across spreadsheets, databases, and business platforms, I can connect it, clean it, model it, and turn it into reporting your team can use confidently. I handle the complete process, from understanding your business questions to developing dashboards and automating recurring reports. My work includes BI and analytics solutions for Insomnia Cookies, Paystar Logistics, Johnson & Johnson, and Advanced Energy. • Insomnia Cookies: Developed 40+ Power BI reports covering sales, operations, marketing, and finance for a business operating across 300+ locations. • Paystar Logistics: Architected and managed a Power BI portal with 30+ automated reports, helping reduce reporting turnaround by 30%. • Johnson & Johnson: Developed Tableau dashboards that made complex consumer BI data easier to explore and understand. • Advanced Energy: Built financial analytics supporting cash flow management and credit reporting, helping reduce report production time by 30%. With Power BI, I can help you build and improve: • Interactive Power BI dashboards and management reports • Executive KPI scorecards and performance monitoring • DAX measures, time intelligence, and business calculations • Power Query transformations, data cleaning, and preparation • Data models, relationships, and reusable semantic models • Sales, financial, marketing, and operational reporting • Budget versus actual, forecast variance, and trend analysis • Power BI Service publishing and scheduled refresh • Automated daily, weekly, and monthly reporting • Troubleshooting and performance improvements for existing reports For Microsoft Fabric projects, I also work with Lakehouse, Dataflows Gen2, and Direct Lake to support data preparation and Power BI reporting.

For SQL, data integration, and reporting automation, I work on: • SQL reporting queries, transformations, and optimization • ETL workflows and combining data from multiple sources • Data cleaning, reconciliation, and KPI validation • Python data analysis, processing, and automation • Integrating spreadsheet, CSV, database, and API data • Replacing repetitive manual reporting with reusable workflows Database and cloud data platforms that can feed BI reporting include Microsoft SQL Server, Azure SQL Database, PostgreSQL, MySQL, Oracle Database, MongoDB, Google BigQuery, Snowflake, Amazon Redshift, and Databricks. My project experience includes PostgreSQL, MySQL, MongoDB, Google BigQuery, and Snowflake. Common business questions I help answer include which stores or customers are most profitable, how actual performance compares with budget, where logistics service is falling short, and how marketing activity connects with sales and customer behavior. My project experience covers retail, e-commerce, logistics, finance, healthcare, telecom, and operations. Reporting examples include revenue and margin analysis, customer segmentation, campaign performance, carrier scorecards, supplier spend, cash flow, and executive financial reporting. I also build AI-powered analytics applications and workflows. These can include natural-language querying of business databases, AI-assisted reporting, and tools that help teams explore data and reduce repetitive analysis. My approach starts with your business requirements. I define the reporting logic, validate the data and calculations, and build dashboards around the decisions your team needs to make. The goal is accurate numbers, clear reporting, and a process that works for your business.
