A deep-dive analytics article on why most KPI “trends” are actually measurement artifacts. Covers the fake-trend taxonomy (schema drift, coverage loss, time shifts, backfills, dedupe, sampling, mix change), a Trend Courtroom evidence protocol, segment invariance tests, and copy-ready checklists + a Trend Report Card for decision safety.

A resilient, fault‑tolerant telemetry analytics pipeline designed to validate, benchmark, and stress‑test high‑frequency sensor data streams under real‑world failure conditions. Includes chaos testing, DLQ repair, GPU‑accelerated ingestion, and end‑to‑end reliability validation for motorsport‑grade telemetry environments.

ValidateLite: A lightweight CLI for database schema validation and data quality checks. Ideal for CI/CD, ETL, and data pipelines.

Esta é uma ferramenta para monitorar alterações no schema de banco de dados PostgreSQL, detectando automaticamente alterações estruturais que podem interromper pipelines ETL, integração de dados ou aplicativos downstream.

Define data pipelines in YAML, execute them asynchronously with Celery, and trace every output column back to its source through automatic lineage graphs. Ships with schema drift detection, JWT auth, HMAC-signed webhooks, immutable audit logs, and a 10-panel Grafana dashboard. 9 Docker services, 206 tests, full CI/CD, live demo.

A technical comparison of two modern data‑engineering approaches for processing customer, orders, and product datasets through an MDM‑aligned pipeline.

A daily ETL pipeline for retail sales data using Python, Pandas, PostgreSQL, and Airflow 3.x. Handles schema drift, cleans and aggregates data, and loads it into a Postgres DB. Includes modular scripts and an Airflow DAG for full orchestration.
