ISP online shop + management system — two apps, one monorepo
Monorepo with two independent Laravel apps: an online shop (Loja) for end-customers to buy plans and vouchers, and a backoffice management system (SGA) for internal operations. They communicate via internal HTTP API — if the shop goes down, the SGA keeps running. Payments via EMIS GPO (Multicaixa Express + Angolan bank card).
The Problem
The company needed both a public-facing shop and an internal management system. Coupling them would mean one failure taking down both. They also needed a PCI-DSS-compliant payment flow in a market where only EMIS GPO is a viable gateway.
Key Features
- ▸Monorepo, two isolated Laravel apps (Loja + SGA) communicating via internal API — failure isolation by design
- ▸EMIS GPO integration: iframe flow ensures card data never touches the app server — PCI-DSS compliant
- ▸SGA on PostgreSQL (complex relations, RBAC, audit logs); Loja on SQLite (simple tables, zero infra overhead)
- ▸Zero CSS framework — namespaced handcrafted CSS per page (.co-*, .ck-*, .cc-*), minimal bundle, no build step for styles
- ▸Signed URLs (Laravel URL::signedRoute) for IDOR protection on all customer-facing links
- ▸Spatie Activity Log for full audit trail in the SGA; Spatie Permission for Admin / Gestor / Revendedor / Staff roles
- ▸Nginx serves static assets directly; PHP-FPM via Unix socket — lower latency than TCP localhost
