SI Developer focused on building end-to-end operational systems
—from real-time data collection to monitoring, control, and UI delivery.
I specialize in:
- Real-time data pipelines (MQTT / Sensor / API)
- Web-based monitoring dashboards
- Flutter-based field operation apps
- System integration across Web, Mobile, and IoT
✔ Design data flow architecture (Sensor → Gateway → Server → UI)
✔ Build real-time monitoring systems
✔ Implement control & command systems (ACK / Retry / Timeout)
✔ Develop field-ready mobile apps (Flutter)
✔ Structure maintainable front-end architecture
- Built real-time monitoring system using MQTT-based streaming
- Processed AML sensor data (battery, load, distance)
