CASE STUDY · SYSTEM
Sublivio Manufacturing Platform
Quote-only custom sportswear system: Next.js storefront, Express API, Prisma/PostgreSQL, frosted route-curtain transitions, and a full RBAC CMS. No retail checkout.
TECHNICAL PUBLICATION
How it is built
USE CASE
Business challenge
A manufacturer needed a public catalog and RFQ flow without pretending to be a shop — sampling, OEM/private label, and staff editing without a page builder.
SYSTEM ARCHITECTURE
Architecture & data
Two Node processes behind Nginx: Next.js on an internal port for store + admin, Express under /api, PostgreSQL as source of truth. CMS pages, menus, homepage JSON, SEO meta, and a permission catalog drive the site. Page transitions use a frosted glass curtain; admin skips the curtain.
BACKEND
API design & authentication
JWT bearer + cookie, bcrypt passwords, RolePermission matrix (SUPER_ADMIN, MANAGER, SALES_REP) with an audit log.
IMPLEMENTATION
Implementation & stack
npm workspaces. Admin dark sidebar with permission-filtered nav. Quote pipeline instead of cart checkout. Hierarchical categories, CMS section editor, media uploads, redirects.
SCALING
Performance & operations
PM2 fork mode, Postgres on localhost, static assets via Next, uploads on disk. This personal site reuses the same product architecture.
