Dennis Furtkevic
I'm a data engineer at Moog Space and Defense. I build pipelines and Power BI reports for a living, mostly in Azure Databricks, SQL, and Python. Before that I spent five years at Cargill, first in food safety and then in data.
At home I point the same tools at my sleep, my server, and horse show results, and I write up what I find here. My family's recipes live here too, written down in one place.
