António Miguel d.

I am an Industrial IoT and Automation Engineer specializing in the design and integration of real-world IoT and industrial monitoring solutions. I connect sensors, smart meters, PLCs and industrial devices using MQTT, LoRaWAN, NB-IoT, REST APIs and other communication protocols, building reliable data pipelines and platforms with Node.js, Python, Node-RED and PostgreSQL/TimescaleDB. My expertise includes Node.js, Next.js, Grafana dashboards, real-time monitoring, alarms, telemetry, data integration and industrial automation, with particular experience in water and wastewater utilities. I have hands-on experience with smart metering, flow and pressure monitoring, leakage detection, wastewater level monitoring, PLC integration and IoT platforms. I focus on production-ready solutions, from field devices and data ingestion to databases, APIs, applications, dashboards and analytics. I can help companies with: • IoT device and sensor integration • MQTT / LoRaWAN / NB-IoT solutions • Industrial and PLC data integration • Node.js / Python / Node-RED development • PostgreSQL / TimescaleDB data platforms • Custom application development for monitoring and data analysis • Grafana dashboards and real-time monitoring • IoT APIs and data pipelines • Industrial automation and telemetry • Water & wastewater monitoring solutions
