I gained 13.6 pounds of muscle in four months. Probably not.

What you'll find here
Skeptic
Default position: show me the evidence. Most things people are sure about — in BI, in fitness, in business — don't survive a careful look at the source data.
Analyst
Twelve years in BI, finance, and operations roles where the job was to translate messy data into a decision someone could actually make.
Engineer
Pipelines, warehouses, dashboards, and the cleanup work that follows. Usually with Python, dbt, Airflow, and one of Snowflake or Postgres.
