About

Independent consultant for enterprise data platforms

I'm Patryk Grabowski, an independent Data Engineering and Business Intelligence consultant specializing in enterprise data platforms. I partner with organizations to design, build and modernize the systems that turn raw data into reliable, decision-ready insight.

My work spans the full data lifecycle — from ingestion and ETL architecture through cloud data platforms to analytics and reporting. I have hands-on, practical experience delivering solutions in enterprise-scale environments where reliability, performance and governance are non-negotiable.

Whether it's migrating legacy ETL estates to the cloud, designing metadata-driven pipeline frameworks, or building the semantic layer behind executive dashboards, I focus on solutions that are maintainable, scalable and clearly documented.
