How the work runs

The pressure that made this worth automating, the steps the system runs, and what came out the other side.

Pressure & Trigger Points

  • Marketing managers struggled to calculate true 90 day customer lifetime value (LTV) across acquisition channels due to separated marketing, order, and return databases.
  • Evaluating cohort retention required custom multi table SQL scripts spanning millions of rows, taking weeks of data engineering sprint cycles.
  • Marketing budget was over allocated to low retention ad campaigns that generated high initial clicks but heavy 30 day return volumes.
