Problem

A team needed a searchable knowledge base with subscription billing that worked well on mobile and desktop.

Solution

Built the UI and core features: content management, responsive layouts across devices, and Stripe subscription billing.

Architecture

  • Angular 8 frontend with Bootstrap-based responsive layouts.
  • Node.js + MySQL for content APIs and user management.
  • MongoDB for flexible document storage.
  • Stripe subscription billing; EJS for server-rendered views.

Impact

  • Delivered a fully functional knowledge base product with billing.
  • Responsive design with CSS media queries for consistent cross-device experience.

Challenges solved

  • Combining Angular SPA with EJS server-rendered views for SEO pages.
