Hi! I'm Maciej

I transform data and
create meaningful reports.

01. About

I'm a Data Engineer with hands-on experience building ETL/ELT pipelines and analytics solutions within the Microsoft ecosystem—from SQL Server and Azure Synapse to Microsoft Fabric and Power BI. I focus on delivering clean, scalable data architectures that translate directly into measurable business value.

My Principles
01

Simplicity by Design

In data engineering, complexity is technical debt. I choose solutions that are easy to maintain and scale—not ones that look impressive in documentation.

02

Data over Intuition

Business decisions should be grounded in facts. I build systems that deliver clean, reliable data exactly when it's needed most.

03

End-to-End Ownership

I don't just write code. I understand the entire process—from data source, through Fabric transformations, to the final pixel in Power BI.

02. Services
