// architecture

Decoupled Monorepo setup. The public storefront (frontend) and administration backend (API & Admin Panel) share a single repository but run fully separate codebases, deploying in isolation. They communicate via a strict REST API and share a single PostgreSQL 16 database and Elasticsearch 9.3 search index.

Decoupled Monorepo

Strict segregation of concerns. Next.js manages presentation and SEO; Laravel & Filament handle databases, queues, and administration

Event-Driven Flow

Critical flows (payments, accounts, alerts) run asynchronously using Laravel Events and Horizon queues. 8 events & 16 listeners

Full-Text Elasticsearch

High-speed catalog search. Utilizes ReindexProductJob for on-the-fly indexing and zero-downtime batch index swapping

Multi-Guard Auth

Separated customer sessions (passwordless OTP code under web guard) and admin sessions (Filament Admin under admin guard)

Dynamic Order Metadata

Flexible form constructor. Products dynamically require custom client fields (e.g. server, name) configured in the admin panel

Multi-Currency Engine

Supports multiple customer currencies with automated exchange rate updates via scheduling CLI tasks
