the pipeline · how the work moves

Every engagement runs the same four moves — from messy source systems to a decision a stakeholder will sign off on.

  1. 01 · ingest

    Wire up the sources

    ETL from SQL Server, Oracle, Excel and SharePoint/API feeds — automated so data lands on a schedule, not by hand.

  2. 02 · model

    Shape the data

    Clean, validate and model in SQL and Power Query / DAX so every metric traces back to a definition people agree on.

  3. 03 · forecast

    Project what's next

    Python and statistical models for depreciation, demand and revenue — the auction model improved forecast accuracy by 25%.

  4. 04 · decide

    Put it in front of people

    Power BI dashboards and review cadences that turn the numbers into calls teams actually make — cutting manual reporting by 70%.
