IoT Prototyping
From hackathon idea to real product — ESP32/ESP8266 hardware, MQTT, and cloud dashboards for teams that want to validate before they commit.
I’ve been building IoT projects in my spare time for years — Home Assistant integrations, ESP8266 and ESP32 sensors, MQTT pipelines, Prometheus and Grafana dashboards driven by real physical data.
At a hackathon, a friend and I built a snow-depth detector using an ultrasonic sensor and an ESP32 shipping metrics over MQTT. The organisers (84codes) hired me to turn this prototype into a hardware demo kit that connected DHT11 sensors to LavinMQ queues, with a Ruby backend forwarding to Grafana — specifically to make conference workshops tangible.
If you have a hardware idea you want to validate before committing to a full build, I can take it from breadboard to deployable prototype.
