PostgreSQL Data Warehouse for 3,000 Vehicles

A fleet organization moved from static report exports to SQL analytics with governed metrics and daily data quality checks.

A multi-region fleet team replaced spreadsheet reporting with a governed Wialon to PostgreSQL warehouse. 3,000 vehicles, delivered over 12 weeks.

The challenge

  • Reports were generated by different teams with conflicting metric definitions.
  • No historical baseline for monthly cost analysis.
  • Dashboard trust dropped because figures changed between reports.

What we built

  • Implemented immutable staging and versioned transformation layers.
  • Built KPI dictionary shared across operations and finance.
  • Added freshness and reconciliation controls for daily quality assurance.

Results

  • Reporting cycle reduced from 3 days to same-day availability.
  • Single KPI standard adopted by operations and finance leadership.
  • Time spent on manual report preparation reduced by 74%.
