TGCast

Telkom’s internal mass email platform. We took it off a legacy CodeIgniter monolith and rebuilt it in Laravel 12, React 19 and TypeScript; email now goes out through queue workers.

Problem

TGCast ran on an ageing CodeIgniter monolith that sent email inside the request, so a broadcast to 10,000 recipients or more blocked until it timed out. The interface did not work on phones, and a Super Admin had no way to revoke a session that had been compromised.

What I built

• Rewrote it on Laravel 12 with Inertia.js and React 19 + TypeScript. The domain model survived; the interface did not, and was rebuilt as responsive components.
• Moved email delivery onto queue workers so broadcasts run asynchronously and in batches instead of blocking the request cycle.
• Built the broadcast and sending module: compose, schedule, per-recipient logs and delivery status.

Result

It is the platform Telkom uses now; the CodeIgniter app is gone. Four of us, weekly sprints.
