About Me

I'm Tuomas, a Senior Analytics Engineer specializing in Databricks and modern data platforms.

My focus is on building production-grade data and analytics solutions on Databricks, with an emphasis on maintainability, performance, governance, and long-term scalability rather than short-term shortcuts.

I bring ten years of experience in business intelligence and analytics, combining Databricks expertise with a strong background in analytics engineering, semantic modeling, dbt, and Power BI.

As a Microsoft Certified Trainer, I also deliver technical training and help organizations establish sustainable development practices and build internal expertise.

Databricks Consulting

I design and build production-grade data and analytics solutions on Databricks, from data ingestion and transformation to governed, business-ready datasets. My focus is on maintainable architecture, reliable pipelines, performance, governance, and development practices that support long-term scalability.

Analytics Engineering and Power BI

I bridge the gap between data platforms and business analytics, building transformation layers, analytical data models, semantic models, and reporting solutions. I bring extensive experience with dbt and Power BI, ensuring that data platform investments ultimately translate into reliable and usable analytics.
