Business Retention & Analytics Dashboard

I built this dashboard to centralize sales data from WhatsApp, providing actionable insights into customer repurchase behavior and retention rates without the need for manual spreadsheets.

Focus

Small businesses often struggle with customer retention. This dashboard tracks these cycles to show which customers are likely to return and which have stopped buying.

Logic & Features:

• Sales Tracking: Converts quick WhatsApp entries into financial reports.
• Retention Data: Identifies inactive customers for re-engagement.
• Authentication: Uses secure magic links requested via chat.
• Performance: Built with Angular 20 and TailwindCSS 4 for fast mobile loading.

Impact & Results

I provided micro-entrepreneurs with enterprise-grade sales visibility. By transforming informal WhatsApp chats into precise retention metrics, the dashboard enabled them to identify at-risk customers and optimize loyalty strategies proactively through data.
