I help companies turn messy operational data into reliable dashboards and internal tools that teams actually use. My work focuses on SQL Server data systems, Power BI analytics, and internal business tools. Many companies already have data, but struggle with organizing it, connecting systems, or building practical applications around it. I help bridge that gap. Typical work includes: • Designing and optimizing SQL Server databases • Building Power BI dashboards and reporting systems • Creating internal tools and admin dashboards (Retool or similar platforms) • Improving slow queries and fixing database performance issues • Structuring data pipelines so reporting and operations run smoothly I often work with companies that have growing data needs but do not yet have a fully structured data platform. Instead of focusing on a single tool, I help build practical data systems that support daily operations. Core technologies: • SQL Server • Power BI (Data Modeling, Dashboards, Paginated Reports) • Retool / Internal Business Tools • Database Design & Data Modeling • Query Optimization & Performance Tuning If you need someone who understands both the database layer and the reporting / application layer, I’d be happy to help.
