    The Proof is in the Pipeline (Part 2) (opens the original)

    Excerpt

    Read excerpt

    All the talk of gradient descent and matrix multiplication that has come with the advent of LLMs really warms my nerdy little math heart. But beyond LLMs (and AI/ML more generally), and as I’ve mentioned before, there’s a surprising amount of math that comes in handy as a Data Engineer despite how much is abstracted via the declarative logic of most modern data processing languages (SQL, PySpark, etc.). I thought I’d take a moment to walk through one such example as the second article in my seri

    Fundamentals of Engineering: Part 1 (opens the original)

    Excerpt · Critical tone

    Read excerpt

    A lot of technical leaders and peers I socialize with often emphasize the importance of understanding the fundamentals of a given engineering discipline (especially data engineering and software engineering), and rightly so. Why? Because the inverse - emphasizing technology and tools over the fundamentals of software or data engineering itself - leads to all kinds of problems in architecture, quality, development processes, and ultimately value realization.
