    Raw files on object storage are great for cheap retention but terrible as a system of record lakehouse architecture adds transactional tables, versioned metadata, and schema contracts on top of the same storage, turning a dumping ground into a reliable analytical platform.

    Using HiveMQ, an industrial plant streamed real-time SCADA data to external machine learning models to fix a failing dosing process. The flexible MQTT pipeline made it easy to add new data inputs without rework. Paired with TimescaleDB, the system scaled to handle continuous telemetry, turning unreliable production into a stable, optimized operation.

  • Why More Data Doesn’t Guarantee Better Insights in Modern Data Systems

    This story was originally published on HackerNoon at: https://hackernoon.com/why-more-data-doesnt-guarantee-better-insights-in-modern-data-systems.


    More data doesn’t mean better insights. Learn how poor data quality, bias, and pipeline issues undermine analytics at scale.

    Volume amplifies both signal and defect equally. Pipelines multiply bad measurements, high-dimensional features invite leakage and spurious correlation, and scale can't fix sampling bias it just hardens it. Better insights come from data that's fit for purpose, stable over time, and validated before it reaches downstream consumers. The goal isn't the biggest dataset; it's the smallest one that still preserves the true shape of the problem.

    Becoming a data science manager exposed gaps no amount of coding skill could fill. After inheriting a team with rock-bottom satisfaction scores and a reputation for unreliable results, I built a 4-pillar framework: fixing output quality, protecting focus with a duty-rotation system, raising the technical bar through knowledge sharing, and overhauling how the team planned and got recognized. Rework dropped from 50% to under 10%. Satisfaction climbed from last place to one of the top departments company-wide.
