I help businesses build fast, reliable, and automated Power BI reporting systems backed by clean Azure SQL models, Microsoft Fabric, scalable ETL pipelines, and optimized semantic models. Slow Power BI dashboards, failed refreshes, and inconsistent numbers are usually not just dashboard problems. They often come from issues in the data model, SQL layer, or ETL pipelines behind the reports. That is where I help. I design, rebuild, and optimize complete reporting systems from raw data to final dashboards turning fragmented data into fast, stable, and decision-ready Power BI solutions. My focus is simple: build and optimize end-to-end data systems that make Power BI fast, reliable, and scalable, even with complex and growing data. Results Delivered: โ€ข Reduced dashboard load times from minutes to seconds โ€ข Fixed broken refresh pipelines and unstable reports โ€ข Built end-to-end reporting systems from ETL to data model to dashboard โ€ข Created consistent KPI layers across multiple reports โ€ข Automated manual reporting workflows โ€ข Delivered dashboards used by leadership for business decisions Core Expertise: โ€ข Power BI dashboards, KPI reporting, performance tuning, and data modeling โ€ข DAX and Power Query optimization โ€ข Power BI Service setup, workspace management, and automated refresh โ€ข Microsoft Fabric, Lakehouse, Warehouse, Dataflows, and modern BI architecture โ€ข Azure Data Factory and ETL/ELT pipelines โ€ข Azure SQL, SQL Server, views, stored procedures, and reporting layers โ€ข SQL query tuning, indexing, and performance optimization โ€ข Multi-source integration including APIs, BigQuery, Snowflake, Excel, SharePoint, and databases โ€ข Star schema design, semantic modeling, relationships, and scalable reporting architecture Why Clients Choose Me: โ€ข Top Rated Plus Upwork freelancer โ€ข $50K+ earned on Upwork โ€ข 100% Job Success with consistent client satisfaction โ€ข Microsoft Certified: Azure Data Engineer Associate โ€ข 7+ years of real-world BI and data engineering experience โ€ข Strong expertise across the full data stack: ETL, SQL, modeling, and reporting โ€ข Focus on performance, scalability, and long-term reliability โ€ข Clear communication with both technical and business teams Some projects need dashboards built from scratch. Others need slow or broken reports fixed. I can help with both. Instead of treating Power BI as a standalone tool, I handle the full system behind it data pipelines, SQL models, semantic layers, refresh logic, and dashboard performance so the final solution is accurate, automated, and built to scale. Whether you need a complete reporting system from scratch or want to fix an existing Power BI setup, I can review the current gaps in SQL, ETL, data modeling, or dashboard performance and help build a solution that works reliably long term.

I build decision-ready analytics systems for small and medium-sized businesses.

My core stack: โ€ข Microsoft Power BI โ€ข Data Modeling (Star Schema) โ€ข DAX โ€ข SQL (PostgreSQL, MySQL) โ€ข ETL pipelines โ€ข API integrations โ€ข Data Warehouse design Typical project workflow: 1. Connect data sources (CRM, databases, APIs, spreadsheets) 2. Build a structured data model or data warehouse 3. Implement ETL pipelines 4. Develop Power BI dashboards 5.
