Descripción

Freelance Senior Data Engineer with 20+ years of experience delivering business-driven data solutions and enterprise analytics platforms across Finance, Sales, and Supply Chain.

I design and implement scalable data architectures ranging from traditional SAP BW data warehouses to modern cloud platforms built on Databricks and Azure.

I have led multiple initiatives enabling self-service analytics and data-driven decision-making using technologies such as Databricks, Azure, Power BI, and SAP. My expertise covers data engineering, BI platforms, platform governance, data observability, and AI-assisted development.

Currently available for freelance opportunities. Passionate about computers and technology, I also develop open-source Python applications for home automation, building data-driven solutions to automate smart home environments.
