Hi past, present or future data professional!

I’ve recently been honing a data engineering skill that might not occur to you—drawing.

When I first started my data engineering job 3+ years ago, any description or information related to my code would be in written form. This meant everything from README documentation to illegible legal pad scribbles would be all I had to inform decisions about design and implementation.

Lately, however, my tasks have grown in both complexity and volume. What I need to convey to myself and my team won't fit on one sheet of paper. And if it did, it wouldn’t make a bit of sense.

So I’ve turned to diagramming tools.

I use tools like Microsoft Visio and Draw IO to create clear depictions of pipelines.

This makes it easy to:

  • Communicate an idea universally - I work with colleagues around the world so sometimes it’s helpful to communicate in a way that isn’t exclusively English
  • Highlight pain points - Applying a different color draws the eye more than an all-caps TO-DO or FIX ME would
  • Make quick edits/rearrange components - have you ever tried rearranging paragraphs or pages of text minutes before a meeting? There’s an entire industry dedicated to this called copyediting—and it can’t be done 5 min before a Zoom call
  • Visualize independent/dependent tasks - this is critical when revising data pipelines that rely on upstream checks to trigger certain associated actions

And, finally, the act of creating an architecture (arch) diagram subtly communicates something: That significant thought went into what you want to propose or present.

Anyone can scribble in a shared doc or reference a notebook of ideas. Taking the time to spend time compiling a visualization demonstrates intent and care.

This translates to you communicating your investment in making sure your build is possible and functional.

Otherwise, it’s back to the (literal) drawing board.

Feel free to scribble down this week’s links.

Thanks for ingesting,

-Zach Quinn

Hi fellow data professional! Once thought to be a purely back office role, data engineering is undergoing a radical transformation and gaining a new responsibility: Front-end deployment. The folks already deploying applications in this capacity are known, incidentally, as forward deployed software engineers or forward deployed engineers (FDEs). Before you worry about needing to learn JavaScript or other web programming paradigms, know that I’m referring to the preparation, deployment and...

Hi past, present or future data professional! As time in 2025 dwindles, I wanted to share what I learned about optimizing design, development and troubleshooting time while working 3 days per week this fall. Quick background: If you’ve been a long-time reader, you’ll know that in March my wife and I had our first child. Consequently, through my employer, I was eligible for several months of parental leave. Anticipating my wife’s return to work (after much needed time off!) I allocated the...

Hi past, present or future data professional! As the winter holidays approach, we’re entering a period of downtime for most orgs. Assuming your employer has hit goals (or accepted losses), allocated coverage for the slew of inevitable vacation requests and maybe even entered a “code freeze”, you’re entering data & tech’s slow season. If you’re working, during this time you may be asked to do any number of “downtime” (actual free time, not data outages) tasks ranging from code refactors to...
