Hi there, I will build the AI integration with proper model selection, prompt engineering, and output validation. The system will process inputs accurately and deliver structured results. I will set up a validation layer between the AI output and your application so uncertain or malformed responses get flagged before reaching the end user. Questions: 1) What AI model or provider do you prefer - OpenAI, Claude, or open-source? 2) What is the expected volume of requests per day? 3) Do you need the AI to work with your existing data or documents? Looking forward to potentially working together. Thanks, Kamran

@Feriver

Hello, I can complete your cross-platform IoT system with end-to-end MQTT communication. The Raspberry Pi will publish sensor data via Python (Paho-MQTT), while a Django/FastAPI middleware preprocesses messages for the Laravel/MySQL backend handling device/user registration and authentication. The React Native mobile app will display real-time sensor readings, connection status, and support graceful reconnections. All code will be modular, commented, and Docker-ready, with deployment instructions to recreate the full stack on a fresh VPS with Mosquitto. The system will be structured to allow future publish/command topics without affecting the current real-time display functionality. Clarification Questions: Should the Django middleware also persist raw messages, or only forward processed data to Laravel? Are there any specific authentication standards for the MQTT broker (TLS, username/password, or token-based)? Thanks, Asif
