How it was built
Why Laravel?
Laravel offered a structured yet flexible foundation, letting me build quickly while keeping code audit-friendly. I used it to scaffold authentication, secure APIs, queue jobs, and extend the platform for future tokens and payment rails.
Real-time engine
Using Laravel Echo and Redis broadcasting, I created a WebSocket-powered interface that delivered live pricing and order execution updates with minimal latency. This meant every user saw the same live order book, wherever they were in the world.
Order matching
I developed a custom queue-based matching engine that processed trades in real time, with rollback-safe database transactions to guarantee accuracy. All trades were tracked in a central ledger for future reporting.
Admin oversight
The admin portal featured permission-based access, real-time dashboards, KYC queues, and audit logs. All privileged actions were logged and accessible for reporting or export.
Lessons learned
- Laravel can handle fintech scale when architected properly
- WebSockets provide a huge UX boost in financial platforms
- Queued, modular architecture is key for safe async trading
- Admin interfaces need the same care and testing as the front end
