REAL-TIME IoT

Backend Engineering

I built the custom ESP32 device and fault-tolerant climate monitoring firmware in C using ESP-IDF, then designed the full-stack platform that carries its temperature, humidity, and barometric-pressure telemetry to this dashboard in real time.

I implemented bidirectional WebSocket communication across the firmware, cloud-hosted backend, and browser client. In addition to receiving telemetry, the dashboard can remotely update the physical device's status light with near-instant feedback.

The web application, ESP32 firmware, and WebSocket server are all public.
