Integrated Business Management
Overview
I completely restructured an existing B2B web management platform developed in React, transforming a system with problematic architecture and incomplete functionality into a modern, scalable and performant solution. I performed complete refactoring eliminating massive code duplications and creating a dynamic pages system with reusable React components that drastically reduce necessary API calls. I completely redesigned the user interface with a modern and responsive design system. I rebuilt the backend architecture implementing advanced security standards and optimized routes for superior performance. The web platform manages customers, orders, warehouse, quotes and billing with automation for barcode labels and document generation.
Key Features
- Reusable React components: universal DataTable and FormBuilder eliminate 60% duplicate code
- Intelligent caching: from 50+ API calls per page to 2-3, 5x faster loading
- Performance: initial bundle -80% (lazy loading + code splitting), from 30s to <3s
- Barcode scanning: fast warehouse movements, minimum stock alerts, real-time inventory
