Roland C.

I help companies turn their data into reliable reporting, dashboards, and business insights. I'm a Senior Analytics & BI Consultant with 10+ years of experience working across data analytics, business intelligence, SQL, data warehousing, and enterprise reporting. My recent freelance work has focused on SQL/PostgreSQL analytics and reporting, including building automated reports and dashboards in Metabase and Cluvio for streaming and other data-driven businesses. ### What I can help you with • SQL analysis and complex business queries • PostgreSQL reporting and data analysis • Metabase dashboards and reporting • BI dashboards and KPI reporting • Automated recurring reports • Data analysis for subscription, revenue, customer and operational metrics • Cleaning and structuring reporting logic • Existing dashboard/report troubleshooting and improvements • Ad-hoc analysis to answer specific business questions • Business requirements → data model → SQL → dashboard I also bring extensive enterprise BI experience from Accenture and Cognizant, including SAP BW, SAP BW/4HANA, S/4HANA Embedded Analytics, BusinessObjects and data warehousing. ### Why clients work with me I combine technical data skills with business understanding. I don't just build charts or write SQL. I first understand what the business needs to measure, translate that into reliable data logic, and then build reporting that people can actually use. I'm comfortable working independently with flexible hours and collaborating directly with business and technical stakeholders. If you already have a database and reporting problem, send me a description of what you're trying to achieve and what tools/data you currently have. I can help you determine the simplest way to get there.
