👋 Hey! I’m Dumky, Developer & Agent Experience Engineer at MotherDuck, the serverless analytics platform built on DuckDB. With a background as a Senior Analytics Engineer, I’m passionate about making data engineering accessible and practical.

I’m also a co-author of Fundamentals of Analytics Engineering and have built everything from €0.02/day Snowplow pipelines to terraformed dbt deployments. When I’m not talking about data, you’ll find me organizing meetups and speaking at conferences about the modern data stack.
