How it works
Situation
The business needed cleaner operational visibility across sales, purchases, procurement, ad spend, revenue, and day-to-day performance. Owners needed a dashboard they could trust without chasing scattered files or manual updates.
Build
I built a role-based internal BI platform where employees enter the data they own and owners review structured dashboards. PostgreSQL acts as the system of record for the operational facts behind the reports.
Result
The system is used internally and gives stakeholders a clearer view of the business. It shows practical BI, operational data capture, and business-facing product engineering.
Key decisions
- Designed the data model around how the business reviews operations, not around a generic dashboard template.
- Kept data entry role-based so responsibility stays close to the people who own each number.
- Used PostgreSQL as the source of truth for operational facts instead of spreadsheet-only reporting.
- Focused on owner-facing clarity while keeping staff workflows direct and repeatable.
