Internal Analytics Dashboard

Company data is spread across Google Analytics, the ERP, the online store, and the CRM. Getting a complete picture means opening 4–5 different systems, manually exporting data, and cross-referencing Excel tables. This process takes hours and makes decisions slow and based on stale data.

A Next.js dashboard deployed on Vercel that connects via API to all company data sources, normalises data on PostgreSQL, and displays it in a clean Chart.js interface. Data updates automatically every hour. The team logs in with dedicated credentials and sees only their department's data. The owner has an aggregated view with all main KPIs on a single screen.

1. API connection to Google Analytics, CRM, e-commerce, POS 2. Hourly data normalisation and aggregation on PostgreSQL 3. Automatic KPI calculation: visits, conversions, revenue, orders, top products 4. Interactive chart display with filters by period and channel 5.
