Flagship SystemIn progress
Alebus
Real-time public transport intelligence platform
Full-StackGoIoT
Alebus turns raw GPS telemetry from transit vehicles into live, actionable intelligence. Location data streams from on-vehicle GPS devices into an EMQX MQTT broker, is processed by a Go backend, and is fanned out through Redis Pub/Sub and WebSocket to a React Native commuter app and a Next.js operator dashboard.
The system is built with Domain-Driven Design across five bounded contexts and ships as seven independently runnable Go binaries, with a full observability stack wired in from day one.
