Full-Stack Developer – Laravel + ESP32 IoT Greenhouse Monitoring & Automation System

Description: I need an experienced full-stack developer to build a self-hosted, local-network (no cloud) greenhouse monitoring and control system, based on a completed technical specification/dissertation. I'll share the full document (architecture, data model, API reference, and UI designs) once we connect. Project overview: The system connects ESP32-based sensor/actuator nodes to a Laravel web application over the local network (no cloud dependency). It monitors environmental conditions and automates irrigation, ventilation, and fertigation for small-to-medium greenhouse operators. Tech stack: Backend: Laravel 10, MySQL Frontend: Bootstrap, Chart.js Firmware: ESP32 (C++/Arduino), communicating via JSON over HTTP Testing: PHPUnit Core features needed: Role-based access control (administrator and operator roles) Live and historical sensor visualization (temperature, humidity, soil moisture, water level, gas level, rain, motion) Device authentication via per-device API key (X-Device-Key header) Configurable warning/critical thresholds with an alert and acknowledgement workflow Manual actuator control panel (irrigation pump, ventilation fan, 2 valves, fertiliser pump) Real-time, rule-based automation engine that reacts to incoming sensor readings Fertigation scheduling (independent of the irrigation cycle) CSV/PDF reporting Support for multiple greenhouses and devices under one deployment ESP32 firmware for authenticated, bidirectional communication with the server Deliverables: Fully functional Laravel web application matching the provided data model and API spec ESP32 firmware for sensor/actuator nodes Automated PHPUnit test suite Basic deployment/setup documentation Ideal candidate: Strong experience with Laravel (routing, middleware, Eloquent, queues) Comfortable with embedded/IoT development (ESP32, Arduino framework, HTTP/JSON) Experience building rule-based automation or event-driven logic Can work from a detailed existing spec and ask good clarifying questions Please share relevant past projects (especially any Laravel + IoT/embedded work) when applying.
