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.

Projects

Write-ups on things I built for myself, with the data, the code, and what didn't work.

  • The Disk That Wasn't Broken

    Two drives looked dead in the same week. One was an SMR drive choking on its own housekeeping, and the other was a bad SATA connection. The server's telemetry told them apart.
