ERP and point of sale

Verified with the local frontend and API

StockBeauty

End-to-end operations for beauty salons and spas: sales, cash, inventory, appointments, commissions and reports.

The challenge

The original product combined PHP with CodeIgniter 3 and Angular 11. The operation needed to evolve without losing critical modules such as sales, cash, inventory, purchasing, appointments, clients, staff and commissions.

My contribution

I modernized the solution as a full stack monorepo: Angular 22 standalone frontend and a NestJS 11 API with Prisma and PostgreSQL. I also consolidated tokens, shared components, tests and quality workflows.

Key decisions

  • Preserve the legacy route contract so the backend could change without breaking the frontend.
  • Use standalone Angular, signals, zoneless change detection and lazy loading for a modern, predictable base.
  • Centralize components, tokens and localization in shared monorepo packages.
  • Separate operations, inventory, administration and reporting with module-level permissions.

The product in use

Outcomes

  • The frontend consumes the modern API while keeping continuity across operating routes.
  • Point of sale, appointments, inventory and administration now share one product experience.
  • The solution can evolve package by package without coupling the frontend and backend again.
