IoT Smart-Meter Gateway Platform

We are looking for professional expertise within the IoT field. We are looking for a full stack developer that has knowledge in both hardware / microcontroller programming but Is also able to present development capabilities in Web Development. We are a startup in the Energy and Photovoltaic sector and are looking for trustworthy and professional people with experience to assist us in future development within a long-term business partnership. If you should only have individual skills from the list below, please mention your skillset explictily. For this project we have a smart energy meter that is connected to raspberry interface which acts as our gateway. The raspberry pi connects via RS485 MODBUS to the smart meter. Project: The connection between the raspberry pi and the smart meter has already been established and the registers can be read. (1) Read the necessary energy data and store them locally in a PostgreSQL DB using Python (2) Using MQTT create and send messages from the PostgreSQL DB to an Azure IoT Hub using secure cetificate based authentication (3) Replicate the local PostgreSQL DB to a centralized master DB as redundancy via VPN (VPN Server is already in pace) (4) Evalute and implement an opensource solution to graphically present the collected data into a Web-Dashboard to display graphs, statistics, and additional historic and current calculations and create reports Assignmment: In your application please send us a short webcam recorded video introducing yourself, your professional field experience, your skills AND explain some comparable reference projects. Knowdledge Required In: Modbus, M-Bus, Real Time Operating Systems, Linux, Windows, MQTT, AMQP, Python, Javascript, PHP, Database Design, Database Implementation, Database Replication, Electrical Engineering, Solution Design Preferable but not required: Microsoft Azure Best regards
