Production patterns, failure postmortems, and architecture decisions from the field.
Your dbt Tests Pass in CI. They Fail in Production. Here is Why.
CI tests pass on seed data but fail in production. This post explains how to structure dbt testing for production behavior — singular tests, source freshness, and contracts.
Data Freshness SLAs: Why Your 9 AM Dashboard Shows Stale Data
Your executive dashboard refreshes at 9 AM but shows data from yesterday. A batch job failed silently at 2 AM, and no one monitors pipeline lag. Here is how to define, measure, and enforce data freshness SLAs.
False Positives in dbt Tests: What Your CI Is Not Telling You
Your dbt tests pass, but distribution shifts, NULL explosions, and referential orphans are reaching production undetected. Here is how to audit your test coverage for the unknown unknowns.
Duplicate Records Are Inflating Your Metrics. Here Is How to Find and Fix Them.
Your de-duplication logic is letting 8–15% of duplicates through. Revenue, MAU, and conversion counts are overreported. Here is how to audit and fix dedup at ingestion, storage, and query time.
Schema Drift Is Eating Your Data Lake. Here is How to Catch It Before It Reaches Production.
Parquet files accept new columns without complaint, and your pipeline silently drops data every time the source adds a field. Here is how to detect, prevent, and survive schema drift in columnar storage lakes.

Building a Clean, Scalable Quant Research Pipeline in Python
Quantitative trading thrives on two things: sound domain logic and solid engineering discipline. A strategy may look strong in theory, but without reproducible pipelines, reliable data flows, and testable models, it becomes impossible to scale.
