“Prêt à lancer votre premier événement ?”

(The project)

A multi-tenant accreditation platform for events: custom registration forms, a visual QR badge designer, bulk PDF generation and encrypted access-control scanning. It started with one event and grew into a reusable SaaS.

(Context)

The whole accreditation lifecycle, as one product.

Each organiser runs their own events, builds registration forms with a drag-and-drop builder, collects visitors, designs and prints QR-coded badges, then controls on-site access by scanning.

A super administrator oversees every organiser, their limits and the global defaults. The platform is a single Laravel 12 application serving a React 19 interface through Inertia.

(Key figures)

multi-tenancy: 3-tier
QR payloads: Encrypted
form builder: Drag & drop
badge scanning: PWA

The decisions that shaped it

One codebase
A single Laravel 12 application serves the React 19 interface through Inertia.js 2, with no split between API and front end.
Inertia monolith
Tenant isolation
Data is scoped by organiser and by event, with event URLs enforced by middleware and role checks reserved for the super administrator.
Soft multi-tenancy
Layered PDF pipeline
Each badge renders from the event’s own template when one exists, with a clean fallback otherwise, before dompdf or TCPDF produces the file.
Dynamic badges
Scanning built against forgery
Visitor identifiers are encrypted inside the QR code, decrypted on the server, checked against the event and the visitor’s status, then logged with gate and time.
Anti-forgery

(How it works)

The accreditation lifecycle

Build the form
Organisers compose a registration form with a drag-and-drop builder; platform defaults are added to every new event.
Collect and design
Visitors arrive manually, by Excel or CSV import, or through public registration, while a Fabric.js designer sets the badge layout.
Generate badges
Each visitor gets a PDF badge with an encrypted QR code, downloadable one by one or streamed in bulk as a ZIP archive.
Scan and log
On the day, the scanning app decrypts the code, checks scope and status, and records the gate, the scanner and the time.
